Answer:

Step-by-step explanation:

I think the attached phôt below is your full question.

<u>And here is my answer: </u>

Surface area of a triangular prism = hight * area of the base

Here we have:

h= 12
Area of the base = 1/2 *2* 1.5 = 1.5

=> Surface area = 12*1.5 = 18

How do i find the inverse function of h(x) =(5-2x^2)/(3x+10)

sergeinik [125]

Inverse function: you need to exchange the position of x and y, in other words,

x = (5-2y^2)/(3y+10) , then, if you need a representation of y with respect to x, then you need to perform some math.

Solve for x. 7^8=7^8×7^x

denis-greek [22]

Answer:

x = 0

Step-by-step explanation:

Apply the exponent rule.
