Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11
Simplify, 15 times 2 divide 3 +11
30divide 3 +11
10+11
answer is 21
Answer:
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:
Then we have the following expression:
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
The answer is the second choice or B. 0.14
Answer:
2
Step-by-step explanation:
The constant -h is half the x-coefficient -4, so is -2. That makes h = 2.
The square of the binomial (x-h) is ...
... (x -h)² = x² -2hx +h²
Comparing x-terms, you see that ...
... -2xh ≡ -4x
... h = (-4x)/(-2x) = 2
