Answer:

x=9

Step-by-step explanation:

Area of a rectangle = length * width

84 = (x-2) * ( x+3); distribute

84 = x²+3x-2x-6; combine like terms and subtract 84 from both sides

0 = x² +x -90

if x= 9 will have 9² +9 -90= 81 +9 -90 = 90-90 = 0 so x=9 works

if x= 10 will have 10² +10 -90 = 100-80= 20 ≠0 so x= 10 does NOT work

if x= -10  and x= -9 will not make sense because we can NOT have a negative measurement

I need help I don’t know how that’s not right.
Leviafan [203]

Answer: v=-81.92

Step-by-step explanation:

\displaystyle\\7+\frac{v}{8} =-3.24\\\\7+\frac{v}{8}-7 =-3.24-7\\\\\frac{v}{8} =-10.24\\\\\frac{v}{8} =-10.24

Multiply both parts of the equation by 8:

\displaystyle\\(\frac{v}{8})(8)=(-10.24)(8) \\\\v=-81.92

Draw a vertical line at the number 4 on your x axis positive side which is x=4

Then anything on the left of this line you just created at x=4 will be less than 4.  But since your inequality is x  less than/equal to 4 it includes 4 as well.
