notice, the first term is 9.5
from there it goes to 11.5, well, how much is it being added to get 11.5?
well 9.5 + 2, is 11.5, so it was added 2 to 9.5
then it goes from 11.5 to 13.5, namely, 11.5+2 = 13.5
and then 13.5+2 = 15.5 and so on
so, the "common difference" or the common addition value, is 2
how do you find the nth term?
well
Draw a two-dimensional representation of each prism. Then find the area of the entire surface of each prism
Answer:
8x+y
Explanation:
3x+4y+5x-3y
Rearrange the terms so like terms are next to each other
3x+5x+4y-3y
Combine like terms
8x+y
I hope this helps!
Step-by-step explanation:
1.4 × 104
i.e (0.7 × 2) × 104
= 1.4 × 104 ≈ 145.6
Let x represent the length
width (w): x
length (L): x
Perimeter (P) = 2L + 2w
320 = 2(x) + 2(x)
320 = x + (x)
320 = x
()320 = x
= x
120 = x
width = x
= ()120
= 40
Answer: 40m x 120m
