Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63
BAM! THE ANSWER!
He rode 2 miles since 4 can go into eight 2 times
4a + 3 = 15
- 3
4a = 12
÷ 4
a = 3
I hope this helps!
Number 3 is there the problem go’s wrong. It should calculate 12 to the peer of two and the get 144 and then divide 144 by 6 to get 24 and then multiply 24 and 4 to get 96
