Answer:
35
Step-by-step explanation:
I multiply 3 and 7 that give 35
Answer:
19
Step-by-step explanation:
10[4 times 10 divided by (6^2-4^2) +1]
First you would multiply 6 x 6 = 36
10[4 times 10 divided by (36-4^2) +1]
Second you would multiply 4 x 4 = 16
10[4 times 10 divided by (36-16) +1]
Third you would subtract 36 - 16 = 20
10[4 times 10 divided by 20 +1]
Fourth you would add 20 + 1 = 21
10[4 times 10 divided by 21]
Fifth you would multiply 4 x 10 = 40
10[40 divided by 21]
Sixth you would divide 40 divided by 21 = 1.90
10[1.90]
Seventh you would multiply 10 x 1.90 = 19
Your answer would be 19.
Hope this helps. I am sorry if you get this wrong.
To help explain how you get A for the answer:
work backwards
5(3a²+11a-4)
multiply everything by 5
5×3a²=15a²
5×11a=55a
5×-4=-20
15a²+55a-20
