Answer:
24
Step-by-step explanation:
We have a system of equations, so we can start with the second equation:
And move y to the other side to isolate x:
Now we can replace x into the first equation:
Notice that we can cancel out the y squared terms:
Now we just need to find x by replacing y into the second equation:
And finally, add them:
Hope this helps.
The 2nd part:
( -2,-1)
(0,3)
( -4,2)
Area is a squared number. We know that from the label we use when we solve problems involving area. Perimeter is a single unit label. This single unit label can also be used to find scale factor, since single unit labels are one-to-one. If the area of polygon F is 36, that means that the single unit measure was a number that was squared to get to the area. Same goes for polygon G. That means that in order to find the single unit measure of each of those we have to take the square root of the area. The square root of 36 is 6, and the square root of 4 is 2. 6:2 is the scale factor, but that can be reduced to 3:1, larger to smaller.
64in/16in = x/18.5
64•18.5= 1184
1184/16x= 16x/16x
1184/16x
x= 74 in
Answer:
Because i have no more information i assume you would like it to be solved.
x < -1 or -1/3 < x < 1
