X(x+2) = 48
x^2 + 2x = 48
x^2 + 2x - 48 = 0
*Use quadratic formulae*
x = 6
Numbers are 6 and 8
Divide total area by area of a gallon of paint:
3025 / 400 = 7.56
Because there is a decimal answer you need to round up tot he next whole number.
You would need 8 gallons of paint.
For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.

Answer: B. (40,40)</h3>
Explanation:
<u>Given Inequalities</u>:
(i) 3x + 8y ≤ 480
(ii) y - x ≤ 20
For first inequality:
(a) y intercept: (0, 60)
(b) x intercept: (160, 0)
- Plot this line with a solid line and shade below.
For second inequality:
(a) y intercept: (0, 20)
(b) x intercept: (-20, 0)
- Plot this line with a solid line and shade below.
The point (40, 40) falls between these two inequalities.
