Answer:
x = 15 or x = -19
Step-by-step explanation:
ΔPQR similar to ΔSQT
SQ / QP = ST / PR
8 / 8+x+5 = x-9 / 21
8 / 13+x = x-9 / 21
(x+13)(X-9) = 168
x² + 4x - 117 = 168
x² + 4x - 285 = 0
(x - 15) (x + 19) = 0
x = 15 or x = -19
Answer:
well i know you have that done now
Step-by-step explanation:
Answer:
Step-by-step explanation:
x < -12, so x+12 < 0
| x-(-12) | = | x+12 | = -x-12
Answer:
a(8) = -12
Step-by-step explanation:
The 8th term in the sequence is when n = 8. Substitute x = 8 into the rule An=-2x+4.
a(8) = -2(8) + 4
a(8) = -16 + 4
a(8) = -12
