Answer:
x^2 +14x+49
Step-by-step explanation:
Area = length * width
= ( x+7) * ( x+7)
FOIL
first: x^2
outer: 7x
inner: 7x
last: 7*7 = 49
Add them together
x^2 +7x+7x + 49
Combine like terms
x^2 +14x+49
<span>The first equation is
x + y = 27
For the second equation, there are twice as many girls (y) as boys (x), so you write:
y = 2x
Now you have a system of equations:
x + y = 27
y = 2x</span>
D) 1:6 because she brought 6 paintbrushes and 36 tubes of oil paint, and we can simplify that to 1/6
4/6 numbers are greater than 2
1/2 chance of flipping heads
Multiply the two fractions together to get the probability
1/2*4/6=2/6=1/3
1/3 probability
The factors of 12 are: 1, 2, 3, 4, 6, 12 The factors of 15 are: 1, 3, 5, 15 <span>The factors of 35 are: 1, 5, 7, 35 The Greatest Common Factor (GCF) is: 1</span>
