Answer:
x= 36
(it is positive since 78 is larger than 42, everything else is correct)
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
Raising both sides to the fifth power, we get:
27(x - 2) = 3⁵
x - 2 = 3⁵ / 27
x - 2 = 3⁵ / 3³
x - 2 = 3⁽⁵⁻³⁾ = 3² = 9
x = 11
No this is not true because 3/5 + 4 equals 4.6 and 3/5 is 0.6
The length of the diagonal should be 18 if I am not wrong!
Step-by-step explanation:
a2+ b2=c2
so 10x10+15x15=the diagonal
100+225=325
325 squared = 18
SA: 2xLxW + 2xWxH + 2xLxH
SA: 2x4.5x20 + 2x4.5x23 + 2x20x23
SA: 180 + 207 + 920
TSA: 1307cm2 (squared)
