Answers
Given:
The function is:
[tex]h(x)=x^2-3x+5[/tex]
To find:
The value of [tex]h(2x+1)[/tex].
Solution:
We have,
[tex]h(x)=x^2-3x+5[/tex]
Putting [tex]x=2x+1[/tex], we get
[tex]h(2x+1)=(2x+1)^2-3(2x+1)+5[/tex]
[tex]h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5[/tex]
[tex]h(2x+1)=4x^2+4x+1-6x-3+5[/tex]
On combining like terms, we get
[tex]h(2x+1)=4x^2+(4x-6x)+(1-3+5)[/tex]
[tex]h(2x+1)=4x^2-2x+3[/tex]
Therefore, the required function is [tex]h(2x+1)=4x^2-2x+3[/tex].

The system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x. The correct option is D.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that The first store will pay her a weekly salary of $250 plus a commission of 12% of her sales. Therefore, the equation can be written as,
Total earning = Weekly salary + 12% of weekly sales
y = 250 + 0.12x
Also, The second store will pay her a weekly salary of $475 plus an 8% commission. Therefore, the equation can be written as,
Total earning = Weekly salary + 8% of weekly sales
y = 475 + 0.08x
Hence, the system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x.

Answers
Answer:
Step 3: x² + 6x + 64 = -8 + 64
Step-by-step explanation:
At step 3 add 64 on both sides to complete the square.
so x² + 6x = -8
becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.
continuing from there, we get
x² + 6x + 64 = 56
we then use a² + 2ab + b² = (a + b)² on the left side to get
(x + 8)² = 56 (solve the equation for x)
by taking the root on both sides
√(x + 8)² = √56
x + 8 = +- 2√14 (separate the equations
x + 8 = 2√14
x + 8 = -2√14
Solving for x
x = 2√14 - 8 or x = -2√14 - 8

Step-by-step explanation:
The area of the given triangle in the image is 74.8m².
What is a triangle?A triangle is simply a polygon with three vertices with three edges.
A scalene triangle is the triangle with no equal sides and angles.
It area can be calculated using the expression;
A = 1/2 × absinθ
Given the data in question;
Length of side a = 15mLength of side b = 11mLength of side c = 22mAngle C = 115°
To determine the area of the triangle, we substitute our given values into the expression above.
A = 1/2 × absinθ
A = 1/2 × 15m × 11m × sin( 115° )
A = 0.5 × 15m × 11m × 0.9063
A = 74.76975m²
A = 74.8m²
Therefore, the area of the given triangle in the image is 74.8m²
