Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
Answer:
yes
Step-by-step explanation:
If you cube a fraction, you cube both the numerator and the denominator, so (3^3)/(5^3) = 27/125.
A^2 + b^2 = c^2
a^2 + (12)^2 = (13)^2
a^2 + 144 = 169
a^2 = 169 - 144
a^2 = 25
Sqrt (a^2) = Sqrt(25)
a = 5
