Step-by-step explanation:

I think you need to do the ones that have a bigger option of 2 first and then make your way to the smallest.

Answer:

solution LHS ;

\( {(3 + 7)}^{2} - 84 \\ (10)^{2} - 84 \\ 100 - 84 \\ = 16\)

Solution RHS ;

\({(3 - 7)}^{2} \\ ( - 4)^{2} \\ = 16\)

I hope I helped you^_^

Answer:

Step-by-step explanation:

(3+7)²−84=(3−7)² =

10²-84=-4²

100-84=16

16=16

Answer: -4/9

Step-by-step explanation:

8/9−(2/3) 2

First, you look at the parenthesis. (2/3)

There is nothing to do with it so you take it out of the parenthesis

8/9 - 2/3 * 2

Now multiply: 2/3 * 2 = 4/3

Now you need to subtract. But the number don't have a common denominator.

Find a common denominator between 9 and 3.

3 can go into 9 three times, so times 3 by 3 to get 9

Now you can subtract 8/9 - 12/9 = -4/9

Answer:

\(-\frac{4}{9}\)

Step-by-step explanation:

2 • 2 = 4

4/3 -----> 12/9

\(\frac{8}{9} - \frac{4}{3} \\\\8 - \frac{12}{9} \\\\-\frac{4}{9}\)

Add the cups of blue cheese to the cups of cream cheese.

2 3/8 + 1

Add the whole number part.

3 3/8

Hope this helps! :)

Answer:

3 3/8 cups

Step-by-step explanation:

when adding fractions and whole numbers together, you can combine like terms, meaning add the whole numbers together separately, and add the fractions separately.

Here we only have to worry about combining whole numbers together. So 2+1= 3, so in total we will have 3 3/8 cups.

Answer:

X=12

Step-by-step explanation:

The quadrilaterals are identical but the one on the right is greater in size and has larger size in proportion.

therefore, 10 × y = 40

or, y= 40÷10

or, y=4

therefore, X= 3 × 4=12

Answer:

Answer:

A. 7m

Step-by-step explanation:

Just add the 4m and 3m.

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

=$2625

Answer:

Using the mean sales value $2400 basic + 3% commision is the better deal

Step-by-step explanation:

As the sales figures are not fixed to a single value lets use the mean (average) value:

In statistics the notation use for this is as follows:

Let the sales value be  

x

Then the mean sales value is:

Answer:

B) 28 inches.

Step-by-step explanation:

After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.

And we want to find the length of the shorter ribbon from the two remaining pieces.

We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:

\(\displaystyle \frac{1}{8}L=9\)

Where L represents the total length of the ribbon.

Solve for the total length:

\(\displaystyle L=72\text{ inches}\)

So, the original length of the ribbon was 72 inches.

Since we threw away 9 inches of it, we now only have 63 inches.

This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:

\((4x)+(5x)=63\)

Solve for x:

\(9x=63\Rightarrow x=7\)

Hence, the two remaining ribbons measure 28 inches and 35 inches.

Therefore, our answer is B.

Answer:

Lesser x = -10

greater x = -2

Step-by-step explanation:

Find the zeroes:-

\(f(x)=(x+6)^{2} -16=0\)

\((x+6)^{2} -16=0\)

\((x+6)^{2} =16\)

\(\sqrt{(x+6)^{2} }=\sqrt{4^{2} }\)

\(x+6=\) ± \(4\)

\(x+6=4\)

\(x=4-6\)

\(x=-2\)

or, \(x+6=-4\)

\(x=-4-6\)

\(x=-10\)

So, \(x=-10, \: or\: x=-2\)
