<span>–10 • 2 ÷ (–4) + 8 • 5
</span>
<span>10 • 2 = 20
</span>
<span>8 • 5 = 40
</span>
–10 • 2 ÷ (–4) + 8 • 5 = <span>– 20 ÷ (–4) + 40
The operation Divide ÷ has to be carried out first.
</span>
<span>– 20 ÷ (–4) = -20/-4 = 5
</span><span>– 20 ÷ (–4) + 40 = </span><span><span>5 + 40 = 45</span>

Answer:
21.15 ft
Step-by-step explanation:
18.7 - 14.3 = 4.4 = pool depth
25.55-4.4 = 21.15 = slide height
2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
