Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B
Answer:
B. (x - 8)(x - 5)
Step-by-step explanation:
If you plugged in x = 5 into the 2nd equation, you would see that you would be multiplying by 0, which would turn everything zero.
Yes your answers are correct :)
Step by step review:
First line has product of 5 and (x+2) so product property is good.
2nd line has division so quotient property is good.
3rd line has equal log with base 2 so equality property is good.
4th line has multiplication so that is also good
5th line has distribution of 5 and 7 so distributive property is good.
Your answer is correct.
Answer:
The answer is: The third option/C
Step-by-step explanation:
The formula for t would be x/7.
In order to find this, we simply follow the order of operations to solve for t.
7t = x ----> Divide both sides by 7
t = x/7
