the answer is 6
hope I helped(:
Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5
Answer:
300x = 435, given x represents the amount of months.
So 435 divided by 300 is 1.45 months for that amount.
Step-by-step explanation:
If it has x intercepts at r1,r2,r3 then the factored form is
f(x)=a(x-r1)(x-r2)(x-r3)
where a is a constant not equal to 0
so
intercepts of -2,0, 1
f(x)=a(x-(-2))(x-0)(x-1)
f(x)=a(x+2)(x)(x-1)
passes through the point (2,16)
find a buy subsituting the point (2,16) into it
16=a(2+2)(2)(2-1)
16=a(4)(2)(1)
16=8a
2=a
the function is
f(x)=2(x+2)(x)(x-1)
Answer:
He messed up on x + 2 = 5 (when he divided both sides by 3.)
He is first supposed to subtract 2 from both sides and you would get 13. Then you would divide both sides by 3 which would get you 4.33 repeating.
