Answer: D
Step-by-step explanation:
The perimeter is all the sides added up
2.5x + 2.5x + 10 + 2 + 10 =>
5x + 22
It is also given that the perimeter is 10.5x
meaning that both these values are equal
5x + 22 = 10.5x
slide right 2 and down 3
OPTION B is the correct answer.
Answer:
y=5x-3
Step-by-step explanation:
slope intercept form=y=mx+b
so
2y-10x=-6
2y=10x-6
y=5x-3
Answer:
n = 1500
Step-by-step explanation:
The sample size is the number of students that were asked
n = 1500
Answer:
<h3>n = 14</h3>
Step-by-step explanation:
Given the sum of the first n consecutive even numbers expressed as
S=n^2+n where n ≥ 2.
If S = 210, then;
210 = n² + n
n² + n - 210 = 0
Factorize
n = -1±√1²-4(-210)/2
n = -1±√1+840/2
n = -1±√841/2
n = -1±29/2
n = -1+29/2 and -1-29/2
n = 28/2 and -30/2
n = 14 and -15
Since n ≥ 2, hence the required value of n is 14
