Answer: -91
Step-by-step explanation:
(2-5)^2-(4*5^2)
Follow the order of operations.
2-5=-3 Which uses the property of parentheses
(-3)^2-(4*5^2)
(-3)^2=9 which uses the property of exponents
5^2=25 which uses the property of exponents
9-(4*25)
4*25=100 which uses the property of multiplication
=9-100 which uses the property of subtraction
=-91
Answer:
Step-by-step explanation:
It is a rectangle, so both sides are equal. Thus 2x+6=5x-9
SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
substitute what you know 16(y)=48
Divide by 16, thus y=3
