Answer:
54
Step-by-step explanation:
2x+2=3x-52
subtract 2 from both sides
2x=3x-54
x=54
<span>(3x^2+3)(4+x^3)
=</span><span>12x^2 +3x^5 + 12 + 3x^3
= </span>3x^5 + 3x^3 + 12x^2 + 12
I believe it is <span>b)the square of the sum of 2 times x and 5</span>
Answer:
The ratio of their areas is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor and the ratio of its areas is equal to the scale factor squared
Let
z -----> the scale factor
In this problem the scale factor is equal to

therefore
the scale factor squared is equal to
