Luke Bryan said the following expressions are equivalent because of the
Distributive Property. Is he correct?
2( 2x2+ 6) = 2x2+ 1

Answers

Answer 1
Luke is not correct

You need to do the problem in order of PEMDAS, so start with parentheses

2 x 2 = 4 + 6 = 10
Distribute the 2 on the outside
2 x 10 = 20

On the other side of the equation start with multiplication

2 x 2 = 4 + 1 = 5

5 ≠ 10

Luke is not correct

The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54
Answer: 54

Explanation: There are only 180 degrees in every triangle. We know that the box in the corner symbols 90 degrees and we have information that the other degree is 36.

90 + 36 = 126
180 - 126 = 54

Daniel and Edwin went to lunch. Daniel’s meal cost $20 and Edwin’s meal cost $18.50. They each left an 18% tip on the price of their own meal. How much did Daniel and Edwin pay in total?

Answers

Answer:

$45.43

Step-by-step explanation:

20 × 0.18 = 3.60

18.50 × 0.18 = 3.33

3.60 + 3.33 = 6.93

The total in tips is 6.93

20 + 18.50 = 38.50

The total meal cost is 38.50

38.50 + 6.93 = 45.43

The total of everything is 45.43

Answer:

The answer is $45.43

A container is shaped like a rectangular prism and has a volume of 72 cubic feet. Give four different set of measurements that could be the dimensions of the container.

Need the answer to all dem ASAP!!!

Answers

Answer:

The formula for the volume of a prism is V = Bh

where,

B is the base area

h is the height.

Since, the base of the prism is a rectangle, therefore, volume of a rectangular prism = (L * B) * h

Assumptions:

Length, L and Width, B cannot be the same.

1.

h = 4 ft

B = 2 ft

L = 9 ft

2.

h = 4 ft

B = 3 ft

L = 6 ft

3.

h = 6 ft

B = 2 ft

L = 6 ft

4.

h = 2 ft

B = 2 ft

L = 18 ft

Answers

Answer:

144 or 72^2

Step-by-step explanation:

You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.

So the first step is

A^2 + B^2 = C^2

2 step,

5^2 + B^2 = 13^2

3 step

5 x 5 = 25 and 13 x 13 = 169

25 + B^2 = 169

4 step

169 - 25 = 144

144 divided by 2 is 72, so 72 x 72 is 144.

If you have an answer 72 squared or 144 both will work.

It does not help that you don't give the answers.

The answer would be 144. Hope this helps!!!!!

Your first term is 4 that is your starting point

Your common ratio is 1/3 so we will be multiplying by that

we will do this six times to get to the seventh term

so the second term is

4*1/3= 4/3

4/3 is our second term so we multiply it by 1/3 to get our third term

4/9 then fourth term is 4/9 *1/3

so 4/27
