Question

Please tell me the answer for the brainliest and please explain how you got them

Answer 1

The equation is like this:8×8+7×3=85 so your answer is 85.

Answer 2

Good Evening,

For the first one, you must distribute the 7 to the numbers inside the parenthesis: 

7 (4x + 2y) ----->28x + 14y 

That would make #1 B.) 28x + 14y

For number 2, you have to use the order of operations, or PEMDAS:

PEMDAS stands for:
Parenthesis   Exponents  Multiplication  Division  Addition  Subtraction

For the second problem, the first step is to do square the 8, because the E for exponents in PEMDAS comes before the rest of the problem:

8² + 7 x 3 ----> 64 + 7 x 3

Then next step is to multiply the 3 and 7 because the M for multiplication comes before the A for addition: 

64 + 7 x 3 ---->  64 + 21

Then you add:

64 +21 ----> 85

That makes number 2 C.) 85

For the third one, just use a calculator to figure out each equation:

Equation 1: 8192 ÷ 4 = 4176 ÷ 2 -----> 2048 ≠ 2088   Not True

Equation 2: 16384 ÷ 8 = 8192 ÷ 4 -----> 2048 = 2048  True 

I can't see all of the answers for number three, but whichever one says that the second equation is correct or the first one is not correct is the right answer for number 3.

Hope this helps!
