Answer:

Step-by-step explanation:
The formula of an area of a rectangle:

<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have

Substitute:

Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em>
<em></em>
combine like terms

Infinite, multiply it by any number divided by itself.
Ex. 1/2*2/2= 2/4
1/2*4/4=4/8 etc.
Answer:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x - 14
Step-by-step explanation:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x + b, -4 = 10 + b, b = -14
y = 2x - 14
Hey there!
Let's call this "number" x. We want four times the sum of this number and 15 to equal at least 120.
Therefore, we want this number times four plus fifteen to be greater than or equal to 120. We have:

Distribute:

Subtract:

Divide:

Your answer is C.
Hope this helps!
the idea of showing that multiplying by 1 is true because as long as A and B follow the same ratio pattern (ie. 1n:2n is the same as 2n:4n) the statement will always be true
