The distributive property: <em>a(b + c) = ab + ac</em>
2(h + 4) + 6(g + 3) + 5h
= (2)(h) + (2)(4) + (6)(g) + (6)(3) + 5h
= 2h + 8 + 6g + 18 + 5h <em>cimbine like terms</em>
= (2h + 5h) + 6g + (8 + 18)
<h3>= 7h + 6g + 26</h3>
Answer:the height of the water increases2 inches per minute
Step-by-step explanation:
The right side of the equation can be rewritten in terms of p as 4p (4p = 4(x^2 +6) = 4x^2 +24)
Now you have (x^2 +6)^2 - 21 = 4p
Replace (x^2 +6) with p
p^2 - 21 = 4p
Subtract 4p from each side:
p^2 - 21 -4p = 0
Rewrite the expression to get p^2 - 4p -21 = 0
Answer:
expression because an equation has to have a plus +×÷ or divsion sign to be an equation
