2x + 4 = xg ....divide both sides by g
(2x + 4) / g = x <==
Answer:
1600
Step-by-step explanation:
Do 400 ÷ 0.25 = 1600
0.25 because of the discount
Check by doing 1600 X 0.25 and it should be 400 which it is
Answer:
Step-by-step explanation:
The four walls have a linear length of (9 m)×4 = 36 m. Of that, the two 1-meter doors are not painted, so the linear length of the painted area is 34 m. The painted area is 2 m high, so the total area being painted is ...
A = LW
A = (34 m)(2 m) = 68 m²
The amount of paint needed for this area is ...
(68 m²) × (1 L/(10 m²) = 6.8 L
If we assume the paint only comes in units of 1 L, then Heather will need 7 L of paint.
The cost of 7 L of paint is ...
(7 L) × ($3.75/L) = $26.25
Heather will need 7 L of paint, for a total cost of $26.25.
Your factoring answer is: (x^2+25)(x+5)(x-5)
