Answer: -4
Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.
I hope that helps.
Answer:
-2
Step-by-step explanation:
First, solve so that y is alone on its side of the equation by dividing both sides of the equation by 12.
12y=(-24)x
y=(-2)x
Therefore, the slope must be -2.

Step-by-step explanation:
4 multiplied by 30 is 120
Answer:
8√21
Step-by-step explanation:
A rectangle has 2 congruent pairs. Those 2 pairs are ST/RU and SR/UT. If that is the case, then that means UV is 5 and SV is also 5. Now we have triangle SRU with a hypotenuse of 10 and a side of 4. Pythagorean Theorem:
4² + b² = 10²
b² = 84
b = 2√21
Segment SR is then equal to b. Now we move on to the area formula:
(2√21)(4) = 8√21
And that is your final answer.
You subtract and find x=10
