Answer:

9

Step-by-step explanation:

Good ol' PEMDAS

First things first, we simplify what is in the parentheses.

4/2 ÷ 2 + (3² - 1)

4/2 ÷ 2 + (9 - 1)

4/2 ÷ 2 + 8

Next we do division. Because there are two instances of division, we work left-to-right. Note that a fraction such as 4/2 is division itself.

4/2 ÷ 2 + 8

2 ÷ 2 + 8

1 + 8

Lastly, it just solving the addition.

1 + 8 = 9

a homeowner is planning an addition to her house. she wants the new family room to be a rectangle with an area of 192 feet. The
kozerog [31]

Answer:

length=16feet  width=12feet

Step-by-step explanation:

This may not be the best way, i just stumbled upon the answer using this.

I knew 14*14=196, which is relatively close to 192.

Then, I took away 2 from one of the 14s and added it to the other 14.

14-2=12    14+2=16

Apparently, 16*12 is 192, so that's the answer.

URGENT ! HELP ! Question is in photo below.

\frac{3(x+5)}{2} \cdot 2=21\cdot 2

Above step we use "Multiplication property of equality"

3(x+5)=42

In the above step we "Simplify on both sides of equation"

3x+15 = 42

In the above step we use "Distribution property"

3x+15-15=42-15

The above step is the result of using "Subtraction property of equality"

3x=27

Above step is result of "Combining the like terms"

\frac{3x}{3} =\frac{27}{3}

Above step is the result of using "Division property of equality"

x=9

Above step is result of "Simplifying fractions on either side of equation"

Which one is the right answer?
azamat

Answer:

D

Step-by-step explanation:

First of all, i mean A and B are out first thing because you don't have enough information to find out if it's true.

C is incorrect because as stated before, not enough information.

<u><em>However,</em></u>

You know that the angles 1-8 are all supplementary, which means that 1 and 2 can be added to make 180 degrees, as so can 3 and 4, 3 and 1. 2 and 4, blah blah blah.

In D, the angles that are being added are supplementary, because the three lines making up that weird figure is adjacent and is parallel to each other.

If you give one of the angles a degree, you know that 180-x with x being that degree, will equal the other angle on the other side of the lines.

Therefore its D.

Edit:

I just realized that theres an angle stated at the top of the screen. Still with that angle given, A and B is incorrect and the answer is still D.
