Explain the difference in the final product of (a + b)^2 and (a – b)^2.

Alja [10]

(a+b)^2 = a^2 + 2ab + b^2
(a-b)^2 = a^2 - 2ab + b^2

The difference in the final product is that if you plug it in the quadratic equation, the value of your b changes.

What’s the answer to this problem I need help

Nataliya [291]

6 ≤ 5(x - 4) -2(-x + 1)

First, distribute 5 to all terms within the first parenthesis, and -2 to all terms in the second parenthesis

6 ≤ (5x - 20 + 2x -2)

Combine like terms

6 ≤ (5x + 2x - 20 - 2)

6 ≤ 7x - 22

Isolate the x. Do the opposite of PEMDAS. Note that what you do to one side you to the other.

Add 22 to both sides

6 (+22) ≤ 7x - 22 (+22)

28 ≤ 7x

Divide 7 from both sides

28/7 ≤ 7x/7

28/7 ≤ x

4 ≤ x is your answer

Use a closed dot (because of the equal underneath) on 4, and go left with an arrow

hope this helps

Andrea has just created a scale drawing of her bedroom room which is 18 feet long by 12 feet wide. The scale drawing shows the l

vivado [14]

Width of the scale drawing is 4 inches

Step-by-step explanation:

We can solve this problem by using the rule of three.

In fact, the actual size of the bedroom are:

$L=18 ft$ (length)

$W=12 ft$ (width)

In the drawing instead, the actual sizes on scale are

$L' = 6 in$ (length in the scale drawing)

$W'$ (width in the scale drawing)

Therefore, applying the rule of three,

$\frac{L'}{L}=\frac{W'}{W}$

And solving for W', we find the width on the scale drawing:

$W'=\frac{L'W}{L}=\frac{(6 in)(12 ft)}{18 ft}=4 in$

So, the width on the scale drawing is 4 inches.
