<u>Answer</u>
t = (sr⁻₂)/5 or
t = (1/5)sr⁻² or
t = s/(5r²)
<u>Explanation</u>
S=5r²t
Dividing both sides by 5r²;
t = s/(5r²)
= (1/5)sr⁻²
= (sr⁻₂)/5

Step-by-step explanation:
4(10n² - 2) - 5(8n² + 7) =
= 40n² - 8 - 40n² - 35 =
= 40n² - 40n² - 8 - 35 = -43 ← the end
Answer:
6
Step-by-step explanation:
We know that the two quads are of similar and the ratio is 1:2, thus
AB/RS = 1/2
3/x = 1/2
x = 6
I got B. I multiplied the numbers in pairs of two and then added the three sums.
