Answer:
4x + 7
Step-by-step explanation:
7x+4-3x+3
First put the like terms together
7x+4-3x+3 = (7x - 3x) + (4 + 3)
= 4x + 7
Answer:
a. 9(2m+7)
b. 4(3r-1)
Step-by-step explanation:
When factoring out the greatest common factor of expressions, first list the factors of the terms. Then, determine the greatest common factor between the two terms. After, "carry" that number out of the expression through division.
a. 18m+63
Start by listing the factors of 18 and 63.
18: 1, 2, 3, 6, 9, 18
63: 1, 3, 7, 9, 21, 63
The greatest common factor of 18 and 63 is 9, so we can carry 9 out of the expression through division:
18m+63
= 9(2m+7)
b. 12r-4
Start by listing the factors of 12 and 4.
12: 1, 2, 3, 4, 6, 12
4: 1, 2, 4
The greatest common factor of 12 and 4 is 4, so we can carry 4 out of the expression through division:
12r-4
= 4(3r-1)
I hope this helps!
B. 87 because the median is when you rank the all the numbers smallest to biggest, and the number in the middle is the median
