Answer:
x=3/2
Step-by-step explanation:
A= l * w =22
A= (3x+1)(2x+1) =22
A= 3x(2x+1) +1(2x+1) =22
A= 6x^2 +3x +2x+1 =22
A=6x^2 +5x +1 =22
A=3/2
Answer:
The second bubble
Explanation
You need to make your exponents equal the other side so to do this;
Distribute the 3 in the exponent "3(x-2)"
Which is 3x-6
And since multiplying exponents adds them, you need a -6 to make the two equal.
So your exponent should equal -6 to make that statement true
Write and solve an equation of ratios:
5 65
--- = ------
4 x
Then 5x = 260, or x = 52. There are 52 girls on the team. Note, as a check, that 65/52 reduces to 5/4, as it must.
-4x+4x +5y +6y = 17-6
11y=11
divide both side by 11 to isolate y
y=1
4x+6(1) = -6
subtract 6 on both sides
4x=-12
divide 4 on both sides
x=-3
Six billion three hundred ninety four thousand and three
