Answer:
W=30m L=90m
Step-by-step explanation:
A =2,700 m²
L=W+60
we know that area of a rectangle is A=L*W so we sustitute what we know
A=L*W
2,700 = (W+60)*W distribute
2,700 = W² +60W subtract 2,700 from both sides
W²+60W-2,700 =0
solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30
L=A/W=2,700/30=90

Answer:
commutative property of addition.
Step-by-step explanation:
In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it.
Mary would be 10 because 10 times 2 is 30 plus 2 more is 32 years.
The answer would be C) 3401 because if we go from right to left on all choices we see for the first option, 4 is in the tens place, the second one has 4 in the ones place, and the fourth option has 4 in the thousands place, so its C).
