Answer:
Total surface area is 630cm
Step-by-step explanation:
Surface area = (Perimeter of the base × Length) + (2 × Base Area) = (S1 +S2 + S3)L + bh
Answer:
(x + 7)^2 = 64
Step-by-step explanation:
x^2 + 23x – 19 = 9x - 4
x^2 + 23x - 9x = -4 + 19
x^2 + 14x = 15 = 0
Completing the square:
(x + 14/2)^2 - (14/2)^2 = 15
(x + 7)^2 - 49 = 15
(x + 7)^2 = 64
Answer:
120
Step-by-step explanation:
Let the required number be x
So,
60% of x = 90
0.6x = 90
x = 90/0.6
x = 900/6
x = 150
