It A because the two mirror each other so you can simplify them to (3x−5)^2.
Answer:
a. m DCB =<DAB=120 opposite angle of the parallelogram are equal
again
BP=PD diagonal bisect it
3x+7=-x+17
3x+x=17-7
4x=10
x=10/4=5/2
b. BD =3x+7-x+17=3×5/2+7-5/2+17=2×5/2+24=5+24=29
Answer:
a = -1 , b = 4 , c = 3 , d = 1
Step-by-step explanation:
The general rules of exponent:

===================================================
Given:

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z
Comparing the right hand side with the left hand side
∴ a = -1
∴ b = 4
∴ c = 3
∴ d = 1
I think the answer is B because the radius is 10 and 10 squared is 100 and 100 times 3.14 is 31.4
