Find (8°f)(3)
f(x) = (x + 2
g(x) = -x^2

Find (8f)(3)f(x) = (x + 2g(x) = -x^2

Answers

Answer 1

Answer:

A) -25

Step-by-step explanation:

[tex]f(x)=|x+2|\\[/tex]

[tex]g(x)=-x^{2}[/tex]

[tex](gof)(x)=g(f(x))=g(|x+21|)\\[/tex]

[tex](gof)(x)=-(|x+21)^{2}[/tex]

[tex](gof)(3)=-(13+21)^{2}[/tex]

[tex](gof)(3)=-(151)^{2}[/tex]

[tex]=-(5)[/tex]

[tex](gof)(3)=-25\\--------[/tex]

hope it helps...

What is the value of y in the equation 2(3y − 15) = 0?

Answers

Answer:

y = 5

Step-by-step explanation:

2(3y - 15) = 0

6y = 30

6y ÷ 6 = 30 ÷ 6

y = 5

the perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area​

Answers

Answer:

63 cm^2

Step-by-step explanation:

p = l + w + l + w

32 = 2l + 2w

32 = 2(w + 2) + 2w

32 = 2w + 4 + 2w

32 = 4w + 4

28 = 4w

7 = w

l = w + 2

l = 7 + 2

l = 9

Check your work:

32 = 9 + 7 + 9 + 7

32 = 32

Correct

A = l × w

A = 9 × 7

A = 63

What is the area of the Triangle?

Answers

Answer 4,200 or 2,100

Area of a triangle is usually found by the formula [tex]1/2(bh)[/tex]

the height is tricky because it is not given. there are some formulas for finding height and stuff, but the easiest way to calculate area without height and a given value for each side is by using the formula [tex](a+b+c)/2[/tex]

So the base is 7 units, hypotenuse 25, and other base 24.
