I am a rectangle, and my area is 80 square inches. My width is 2 inches shorter than my length. What is my perimeter?

pshichka [43]

Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

Assuming that x=-2 and y=3 evaluate xy-x^3

meriva

(-2^3) = -8.
-2 times 3 = -6.

The expression is now -6 - (-8).

-6 + 8 = 2.

The answer should be 2.

The midpoint of AB is M(7. – 7). If the coordinates of A are (8,-6), what are the

IRISSAK [1]

Answer: B = (6,-8)

Step-by-step explanation:

first the midpoint formula is $(\frac{x1+x2}{2},\frac{y1+y2}{2})$

then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

$\frac{8+x}{2}=7$

then solve it like an equation:

$8+ x=14\\x=6$

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

$\frac{-6+y}{2} =-7$

then solve it like an equation:

$-6+y=-14\\y=-8$

∴ the answer is x=6, y= -8

which is expressed as a point, B(6,-8)
