Answer:

12 1/4

Step-by-step explanation:

(7 + X) × 8 - 4 × X = 56

7 + X × 8 - 4 × X = 56

7 + 8X - 4 × X = 56

7 + 8X - 4X = 56

7 + 4X = 56

4X = 56 - 7

X = 49/4

X = 12 1/4

X squared plus 8 squared equals 9<br> What is X?

BabaBlast [244]

Answer:

x = $i\sqrt{55} , -i\sqrt{55}$

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- $\sqrt{-55}$

Simplify

x = $i\sqrt{55} , -i\sqrt{55}$

Hope this helps!

Name the prism in each case given that all lateral faces are rectangles and the bases are: Equilateral triangles

Cloud [144]

This is a triangular prism.

The lateral faces are triangles; this means that the two bases are parallel to one another. This makes it a prism instead of a pyramid.

The bases being triangles makes it a triangular prism.
