Here, I think I can help you out:
1. 21 ÷ 3
= 7
Therefore, the length is 7cm².
2. 35 ÷ 7
= 5cm²
- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.
7. All sides of a square are the same length.
7 x 7
= 49cm²
9. 2 x 3.5
= 7m²
- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)
Answer:
26
Step-by-step explanation:
2(9)-(-3)+5
2(9)+3+5
18+8
26
You're probably supposed to find the value of p and not x, which is impossible to do.
Expanding gives
We're told that
which we can use to solve for p:
Answer:
2(u-5)-6u
2u-2•5
2u-10
2u-10-6u
2u-6u-10
-4u-19
