The answer is 988 square inches. L=23 W=10 H=8
The equation for surface area is 2(L x W) + 2(L x H) + 2(W x H)
Next, you need to substitute the values into the equation to get:
Surface area= 2(23 x 10) + 2(23 x 8) + 2(10 x 8)
Now finish solving the equation to get an answer of 988 square inches!
The quotient to 1.44 and 0.4 equals to 3.6
I supppose the answer is F(X)=X²+4, you can use the vertex to confirm.
The answer is just do easy subtraction 3/4
First, we obtain the gradient (slope) of the first parallel line

Recall that since both lines are parallel, we have that,

Thus

Hence, we can find the equation of the parallel line given that it passes through the points (-4, -3)
Using
