Answer:

4x^3+y
Step-by-step explanation:
log x - log 6 = 2 log 4
log(x) - log(6) = 2 log(4)
Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):
log(x / 6) = 2 log(4)
Rewrite the right side, using the property n log(a) = log(aⁿ ):
log(x / 6) = log(4²)
log(x / 6) = log(16)
Cancel the logarithms (i.e. take the exponential of both sides):
exp(log(x / 6)) = exp(log(16))
x / 6 = 16
Solve for x :
x = 6 × 16
x = 96

=============================================
Explanation:
We'll need the tangent rule
tan(angle) = opposite/adjacent
tan(R) = TH/HR
tan(30) = TH/54
sqrt(3)/3 = TH/54 ... use the unit circle
54*sqrt(3)/3 = TH .... multiply both sides by 54
(54/3)*sqrt(3) = TH
18*sqrt(3) = TH
TH = 18*sqrt(3) which points to choice A as the final answer
----------------------
An alternative method:
Triangle THR is a 30-60-90 triangle.
Let x be the measure of side TH. This side is opposite the smallest angle R = 30, so we consider this the short leg.
The hypotenuse is twice as long as x, so TR = 2x. This only applies to 30-60-90 triangles.
Now use the pythagorean theorem
a^2 + b^2 = c^2
(TH)^2 + (HR)^2 = (TR)^2
(x)^2 + (54)^2 = (2x)^2
x^2 + 2916 = 4x^2
2916 = 4x^2 - x^2
3x^2 = 2916
x^2 = 2916/3
x^2 = 972
x = sqrt(972)
x = sqrt(324*3)
x = sqrt(324)*sqrt(3)
x = 18*sqrt(3) which is the length of TH.
A slightly similar idea is to use the fact that if y is the long leg and x is the short leg, then y = x*sqrt(3). Plug in y = 54 and isolate x and you should get x = 18*sqrt(3). Again, this trick only works for 30-60-90 triangles.
At janices age she is not only 5 times older than ross, but she is 28 years older than ross. How old is janice?
Answer:
35 years old
Step-by-step explanation:
Let Janice's age = j.
Let Ross's age = r.
j = 5r
j = r + 28
Set the equations equal to each other.
5r = r + 28
4r = 28
r = 7
j = 5r
j = 5(7)
j = 35
Answer: 35 years old
Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125. Estimate the number of months that Zea can continue this pattern until she reaches her credit limit.
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.
What is a credit card?A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.
Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.
The distinction between the installment made and the charges done will be given as,
Difference = $200 - $125
Difference = $75
Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.
⇒ $2,000 / $75
⇒ 26.667 ≈ 27
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

Find the triangle sum theorem
Answer:
x=37
Step-by-step explanation:
a triangle is equal to 180°. so if you already have 50+56 then you have 74° left for 2x. and 74/2=37
Answer:
x=37 because 56+50=106 180-106=74 74÷2=37
Find the area of the shaded part of the triangle below. Round to the nearest tenth if needed.
Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5

Which statement is true about the following pair of rectangles?
Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.
Answer:
Option D
Step-by-step explanation:
the height of the first rectangle ( 30 ) over the height of the other rectangle ( 3 ) is 30/3 and equals 10
the length of the first rectangle ( 60 ) over the length of the second rectangle ( 6 ) is 60/6 and equals 10
the ratio of the sides of both rectangles are equivalent therefore the are similar

Please help me solve this
Answer:
1st pic:
x = 61
left angle = 125 degrees
right angle = 55 degrees
2nd pic:
n = 14
left angle = 78 degrees
right angle = 102 degrees
Step-by-step explanation:
1st pic:
use the following equation ⇒ 2x + 3 + x - 6 = 180
combine like terms ⇒ 3x - 3 = 180
add 6 on both sides ⇒ 3x - 3 + 3 = 180 + 3 ⇒ 3x = 183
divide both sides by 3 ⇒ [tex]\frac{3x}{3} = \frac{183}{3}[/tex]
x = 61
solve the angles by subtituting 61 for x
left angle = 2x + 3 ⇒ 2 x 61 + 3 ⇒ 125 degrees
right angle = x - 6 ⇒ 61 - 6 ⇒ 55 degrees
2nd pic:
use the following equation ⇒ 4n + 22 + 8n - 10 = 180
combine like terms ⇒ 12n + 12= 180
subtract 12 on both sides ⇒ 12n + 12 - 12 = 180 - 12 ⇒ 12n = 168
divide both sides by 12 ⇒ [tex]\frac{12n}{12} = \frac{168}{12}[/tex]
n = 14
you can find the angles by substituting 14 for n:
left angle = 4n + 22 ⇒ 4 x 14 + 22 =78 degrees
right angle: 8n - 10 ⇒ 8 x 14 - 10 = 102 degrees
