6a-11=13
add 11 to both sides cross out -11 with +11
13+11 =24
6a=24
divide 6 on both sides
a= 4
4 feet is bigger because there is only 3 feet in 1 yard
Answer:
geometric
x=number of terms
∑ 2(-5)^(k-1)
k=1
Step-by-step explanation:
the sequence has a ratio of -5 (2*-5=-10, -10*-5=50)
x=number of terms
∑ 2(-5)^(k-1)
k=1
for this i don't know what the last term is since it doesn't show in the question but just find 2(-5)^x and x will be the top term
I think that this is the answer if you are combining like terms 4x^3+5x^2+2x-6.
