I am learning this right now but in two hours I will tell you
Answer: Estimate: 36 ? units ? miles per hour ? feet per second?
Exact: 35.32142857 but if you are supposed to use significant digits, 35.32 is probably good.
Step-by-step explanation: For the estimate, round off the fractions to whole numbers, so multiply 6 x 6 to get 36
For exact I converted the mixed numbers to improper fractions, 5 3/4 = 23/4 and 6 1/7 = 43/7. Then multiplied the numerators 23 x 43= 989. And denominators, 4x7=28.
Divide numerator by denominator 989/28= 35.321428571
2(l+w)=P
72 x 2= 144
240 - 144= 96
96/2= 48
your answer would be 48in.
<u>check
</u>2(72+48)= 240
144+96= 240
240=240
Answer:
no 15x — 20xy as 5x(3— 4xy is not correct
Step-by-step explanation:
15x — 20xy ≠ 5x(3— 4xy)
there are not equal because 5x(3 - 4xy) =
when you simplify the bracket, you will have
15x - 20x²y
