X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0

x = -7      or       x = -1

I need help ASAP :/ I need the explanation
PtichkaEL [24]

Is 17x-2 supposed to be angle T?   This is a bad question; demand better from your teachers.

Let's assume 17x-2 = angle T.    S is a right angle because it's subtended by a diameter, Thales' Theorem.  R is half 116 degrees, so 58 degrees.  T  is complementary, T=90-58=32 degrees.

17x -2 = 32

17x = 34

x = 2

Plzz help fast /The volume of the prism
iragen [17]

Answer:

1716 m^3

Step-by-step explanation:

We can find the volume of a triangular prism by thinking about it like this - it's half of a rectangular prism. It's just be cut diagonally. So we can imagine that the measurements of the potential rectangular prism are 6m x 26 m x 22m.

Volume of rectangular prism:

6*26*22 = 3432

Volume of triangular prism:

1/2 of rectangular prism - 3432/2 = 1216
