You multiply the number 8 to each term in the parentheses.
8 x 5g = 40g; 8 x 5 = 40; 8 x (-2) = -16
Combine these together and it would be 40g + 40 - 16

Answer: Choice A</h3>
This is because we're adding -6 to each term, i.e. subtracting 6 from each term, to get the next term
- -2+(-6) = -8
- -8+(-6) = -14
- -14+(-6) = -20
- -20+(-6) = -26
and so on. The gap between adjacent terms is the same width. We say that the common difference is d = -6.
Direct variation means that changes in x will result to changes in y. If x increase, y also increases and vice versa.
y = kx
k = y / x
y = 45 ; x = 40
k = 45/40
k = 1.125
y = 1.125x
y will increase by 1.125 interval of x.
