Answer:
QR = 5.
Step-by-step explanation:
Because the parallelograms are similar then the corresponding sides are in the same ratio.
So AB / PQ = BC / QR
9/3 = 15 / QR
15 / QR = 3
QR = 15/3
= 5. (answer)
I think it’s 40 i’m not sure tho
Answer: x=9,-1
Step-by-step explanation:
First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8
Those numbers would be -9 & 1
-9+1=-8
-9x1=-9
Now we have
(x-9)(x+1)
x-9=0 x+1=0
+9 +9 -1 -1
x=9 x=-1
Answer:
v = -16
Step-by-step explanation:
<u>→Distribute the 5 to (-7v - 11):</u>
14 - 10v + 11 = 20v - 35v - 55
<u>→Add like terms:</u>
25 - 10v = -15v - 55
<u>→Add 15v to both sides:</u>
25 + 5v = -55
<u>→Subtract 25 from both sides:</u>
5v = -80
<u>→Divide both sides by 5:</u>
v = -16
