Answer:
w=3
Step-by-step explanation:
The area of the triangle is given by
A = 1/2 bh
the base is 5 and the height is 3
A = 1/2 (3) * 5 = 15/2 units ^2
The area of a rectangle is
A = l*w
A = 5w
The area of the triangle = 1/2 the area of the rectangle
15/2 = 1/2 *5w
15/2 = 5/2 w
Multiply each side by 2/5 to isolate w
2/5 * 15/2 = 2/5 *5/2 w
3 =w
I think the answer is 3.
I just guessed.
it’s b.4
hopes this help you
80
720/P = 9/1
Cross multiply.
9P = 720
P = 720/9
P = 80
f(g(2)) = 44
g(2) = 3(2) + 1 = 7
Plug 7 into f(x) since g(2) = 7
f(7) = 7² - 5 = 44
12 is 52 i think. i am not sure about 11.
im so sorry i know 11:(
I hope this helps on 12 tho
