Answer:
I got -64
Step-by-step explanation:
The begging multiplication is 0 and subtract -7 is becomes just -7 then add 3 and it is -4 to the third power is -64
90x+60y=72
60y=-90x+72
y=-1.5x+1.2
then create a graph using this formula.
Hope this helps!
Answer:
<h2><u>7</u>x - <u>7</u>y + <u>21</u> </h2>
Step-by-step explanation:
7(x - y + 3)
=> 7 × x - 7 × y + 7 × 3
=> <u>7</u>x - <u>7</u>y + <u>21</u>
Answer:
The GCF is going to be 30
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 21, 2 × 3 × 3 × 5= 90
The prime factorization of 28, 2 × 3 × 5 × 7 = 210
The common factors are, 2, 3, and 5. We multiply those to get the GCF.
2 × 3 × 5 = 30
Answer:
