Step-by-step explanation:
solution.
Let S represent side of the equilateral triangle.
perimeter of equilateral ∆ =3×S
Therefore,if we let width to be represented by W
Width of rectangle=W
Length of rectangle=2W
one side of equilateral triangle= W+8
Therefore after analysing the question, the true statement is; The length of the rectangle is 2W
It's right triangle 45 45 90
The sides in this triangle<span> are in the ratio 1 : 1 : 1√2
if one side = </span>2√2 then b = 2√2
hypo. a = b(√2) = 2(2√2) = 4√2
answer
a = 4√2
b = 2√2
Answer:
y=-x+2.5
Step-by-step explanation:
Find n first.
n+10= 40
Subtract 10.
n= 30
Plug in n.
30-25= 5
The answer is 5.
I hope this helps!

if you want to solve it without a graph you're going to need to use the cubic formula, I'm unsure how else to solve it
