Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is 
Since there is no base down payment or anything the equation i think would just be 35m = c
If there was say a one time payment of $20 and then the monthly payments it would look like 20+35m=C
I hope this helps :)
Answer:
the answer is B, complementary angles
Step-by-step explanation:
complementary angles are two angles that add up to 180 degrees
105 + 75 = 180
Answer:
x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3
= -3

4 • (2 + 5)^2 - 52
= </span>4 • (7)^2 - 52
= 4 • 49 - 52
= 196 - 52
= 144
if multiply by 2
4 • (2 + 5)2 - 52
= 4 • (7)2 - 52
= 4 • 14 - 52
= 56 - 52
= 4
