1. 540
2. 480
3.525
you do the rest

b = (a - 3)²
Our aim is to get <u><em>a</em></u> to be alone
1) First we get rid of what's in the brackets. So we subtracts each side by 3. Of course, the opposite of subtracting is adding:
b+3 = a²
2) Now we get rid of the squared in a. Opposite of squaring is square rooting.

3) There we have it. a is now by itself. We can test if we're right by substituting.
Lets make a=2
b=(a-3)²
b= (2-3)²
b= 1
NOW:


Answer:
it's simple substitution
Step-by-step explanation:
1. (7)(2)/2= 14/2=7
2. (5)-(8)/4=
3. (6)-(1)+6=11
4. (19)+(1)^3=21
Answer:
115.2
Step-by-step explanation:
Take 345.6 miles and divide it by 3 getting your answer. Have a great day!
A dilation is basically a factor of enlargement or reduction, where you multiply the factor for the dilation.
So,
Multiply the numerator 5 by the factor of 8.
5*8= 40
40/8 ft^2= 5 ft^2
The new area if 5 ft^2.
I hope this helps!
