Answer:
x=2
Step-by-step explanation:
To solve this, you must isolate x. To do this, divide both sides by 425 because that is what x is being multiplied by (and dividing is its opposite). Then, you get the answer, x=2.
Answer:
36
Step-by-step explanation:
make proportion giants to elves
120/144 = 90/x cross multiply
120x =144*90
120x =12960 divide by 120
x = 108
so if there are 90 giants in the theater there are 108 elves also
considering that total 144 elves can be in the theater subtract 144 and 108 so 36 more elves can be admitted
Lets x = width
height = 2x - 4
A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7
so width = 9
height = 2(9) - 4 = 18 - 4 = 14
answer
width = 9 in
height = 14 in

Step-by-step explanation:
If you look up the definition of integers you see:
integer
[ˈin(t)əjər]
NOUN
integers (plural noun)
a whole number; a number that is not a fraction.
"integer values"
a thing complete in itself.
So C and D are correct.
Answer: 4 units.
Step-by-step explanation:
Once each point is plotted, you get the rectangle attached.
You can observe in the figure that the base of the rectangle is its longer side.
Since the length of the base of the rectangle goes from 
to 
, you can say that the lenght of the base is the difference between 3 and -1.
So, you need to subtract this two coordinates, getting that the lenght of the base of the rectangle attached is:
