5(x)=10x+8 so x is equal to -3
Answer:
f = -8
Step-by-step explanation:
7(f+3)+9=5(f-2)-3f
7f + 21 + 9 = 5f - 10 - 3f
7f + 30 = 2f - 10
5f = -40
f = -8
Answer:
Step-by-step explanation:
h^2=x^2+y^2, since this is a square x=y=s so
220^2=2s^2
2s^2=48400
s^2=24200
s=24200^(1/2)m (exact)
s=155.56m (rounded to nearest hundredth of a meter)
One hectare is equal to 10000m^2
A=24200m^2(h/10000m^2)
A=2.42 hectares
27x² and 81x⁵
81 = 27*3
x⁵ = x²x³
81x⁵ = 27*3*x²x³= (27x²)*3x³
We can see that 81x⁵=(27x²)*3x³ includes as a factor 27x²,
so GCF is 27x².
