Answer:

51 in²

Step-by-step explanation:

formula of a triangle: [tex]\frac{1}{2}[/tex]bh

the base is 3 and the height is 7

1/2(3)(7)

1/2(21)=

10.5

Since there are 4 of these same triangles, we multiply by 4.

10.5 · 4 = 42 in²

formula of a square: bh

base is 3 and height is 3

(3)(3) =

9 in²

add them together and you get your answer of 51 in²

Answer:

t_n =a +(n-1)d

t_100 = 2+ (100-1)6

Answer:

x = 2

y = -3

Step-by-step explanation:

2x + 2y = -2, then 2y = -2 - 2x

3x - 2y = 12, then 2y = 3x - 12

so:

-2 - 2x = 3x - 12

add 2x and 12 to each side of the equation:

5x = 10

divide both sides by 5:

x = 2

2y = 3(2) - 12

2y = -6

divide both sides by 2:

y = -3

A) 33+3i

Step-by-step explanation:

Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd.

15−15i+18i+18

combine like terms

(15+18)+(−15i+18i)

simplify

33+3i

Answer:

x = 2√58

Step-by-step explanation:

Answer:

I wanna say 7 but I could be wrong

Step-by-step explanation:

The number of triples is 6.

A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For the given situation,

Total number of hits = 18

Doubles + triples = 18

Let x be the number of triples. Then

Number of doubles = 18-x

Number of bases for doubles = 2 bases

Number of bases for triples = 3

The equation for the above situation is

⇒ [tex]2(18-x)+3x=42\\[/tex]

⇒ [tex]36-2x+3x=42[/tex]

⇒ [tex]x=42-36[/tex]

⇒ [tex]x=6[/tex]

Hence we can conclude that the number of triples is 6.

Question: Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 4 cm 15 cm a. 15.5 cm

b. 30 cm

c. 60 cm

d. 34.5 cm​

Answer:

d. 34.5 cm

Step-by-step explanation:

Applying

Perimeter of the right triangle (P) = a+b+c

P = a+b+c.................... Equation 1

But we can find the hyotenuse (a) using pythagoras theorem

a² = b²+c²

a = √(b²+c²)............... Equation 2

Substituting equation 2 into equation 1

P = √(b²+c²)+b+c................... Equation 3

From the diagram,

Given: b = 4 cm, c = 15 cm

Substitute these values into equation 2

P = √(4²+15²)+4+15

P = √(241)+4+15

P = 15.5+4+15

P = 34.5 cm

Hence the right answer is d. 34.5 cm
