Answer:
72
explanation:
Just took the test
Answer:
A 72$
and a good day
(7√)^2 = _____
in simplest form.
By the Power of a Power rule, (712)2=722 .
So, 712 must equal______
in radical form.
For this case we have:
By properties of the radicals
So:
.
Now, for power properties we have:
Thus,
So:
in its radical form
Answer:
in its simplest form.
in its radical form
Answer:
in its radical form
explanation:
Answer:
(7x²y + 4xy²+ y³ + 1) is the answer.
Step-by-step explanation:
We have to write the simplified form of the given expression.
(6x²y + 4xy² - 2y³ + 6) + (x²y + 3y³ - 5)
We will collect the similar terms first
(6x²y + x²y) + 4xy²- (2y³ - 3y³) + (6 - 5)
= 7x²y + 4xy²+ y³ + 1
Therefore, (7x²y + 4xy²+ y³ + 1) will be the answer.

Choose exactly two answers that are correct.
A.
five added to the quotient of 4 and a number
B.
the product of 4 and a number increased by 5
C.
four times the sum of a number and 5
D.
five more than the result of multiplying 4 by a number
5.Which variable expression represents the word phrase?

A.
7 – (m + 4)
B.
(m + 4) – 7
C.
7 – (m – 4)
D.
7 – m + 4
Answer:
The answer is d
Step-by-step explanation:
b. 70 <= 82 + 88 + n / 3 <= 85; 80 <= n <= 85
c. 80 <= 82 + 88 + n / 3 < 85; 70 < n < 85
d. 82 <= 80 + 85 + n / 3 <= 88; 70 <= n <= 85
Answer : option A
Jackie scored 82 and 88 on her first two quizzes
Let n be the score of third quiz
Average of 3 quiz =
average between 80 and 85, inclusive.
so average lies between 80 and 85
Question says 80 and 85 inclusive. so we use <= or >= symbol
So inequality becomes
( multiply all sides by 3)
(subtract all sides by 170)
so option A is correct
Answer:
A.
Step-by-step explanation:
The answer is A.
