The answer is C. (x+6)(x+8)
Answer: 3
Step-by-step explanation:
Pretty sure it's x= -2. multiply everything by 3
then combine.
10= 6^x you can work it like a log and minus 10 from each side.
0= -4^x
so what raised to the power gives you -4? x=-2
Answer:
32/166=9/29 if two ratio are equivalent to other
Answer:
x = 14
Step-by-step explanation:
See the diagram of the triangle attached.
We have Δ RST where, ∠ RST = 7x -54 and ∠ SRT = ∠ STR {Since, given that, RS = ST}
Now, if ∠ STU = 8x, then ∠ STR = 180 - 8x {Since, ∠ STU and ∠ STR are supplementary}
So, ∠ SRT = ∠ STR = 180 - 8x
Now, from Δ SRT, ∠ RST + ∠ SRT + ∠ STR = 180
⇒ 7x - 54 + 180 - 8x + 180 - 8x = 180
⇒ 9x = 126
⇒ x = 14 (Answer)
