Find all solutions for the equation. x^2 +4x -8 =0

kondor19780726 [428]

The answer is actually D. Since 2.5 is a side of each tiny block, there is 3 sides that you are going to multiply together. There is 5,2 and 4 because we are multiplying the length,width and side. So the length is 2.5*5=12.5 which was correct. The width is 2.5*4=10 which you had but you crossed it out. Then lastly you are looking for the side of the shape. 2.5*2=5. Now that I have everything I just need to multiply everything together. 12.5*10*5=625 in³. I hope this helped you!

Line t passes through points (10, 4) and (7, 9). Line u is parallel to line t. What is the slope of line u?

Margarita [4]

Answer: 3/5

Step-by-step explanation:

concept to know: the slope of perpendicular line is always opposite reciprocal

----------------------

Step 1. Find the slope of line t

(y2-y1)/(x2-x1)

=(4-9)/(10-7)

=-5/3

-------------------

Step 2. Apply the concept

Opposite reciprocal of (-5/3)=3/5

Hope this helps!! :)

Find the area of this circle. Use 3.14 for pi

aalyn [17]

The area of a circle is given by the formula:

A = $\pi$ r^2

Since $\pi$ = 3.14, and r = 6, sub these values into the equation,

A = 3.14 x 6^2
= 113.04

Hope this helped!
