If not I am sorry.
QR || ST & QT=RS
That could be an isosceles trapezoid. Don't check this one.
QR=ST & QR || ST
Congruent Parallel sides. CHECK ME.
QT || RS & QR=ST.
Basically the same as the first, don't check.
QR=ST & QT=RS
Quadrilateral with equal opposite sides is a parallelogram. CHECK ME
QR=ST & ST=ST
ST=ST is not news. Congruent opposite sides. Don't check me.
The answer to your question is B.
4 - 7x = 8 + x
We can find the value of x by making the following changes:
<u><em>Add 7x to both sides</em></u>
4 = 8 + 8x
<em><u>Subtract 8 from both sides</u></em>
-4 = 8x
<em><u>Divide both sides by 8</u></em>
x = -0.5
Answer:
n = 3
Step-by-step explanation:
9{n+2(n-2)} = 45
Start with the numbers on the inner most pair of parentheses
Multiply (n-2) by 2
9[n+2n-4] = 45
Add what is inside the parentheses
9[3n-4] = 45
Multiply
27n-36 = 45
Add 36 to both sides
27n = 81
Divide both sides by 27
n = 3
Hope this helps!
