Step-by-step explanation:
8x + 7 + 7x - 2=90=>
=> 15x+5= 90
=> 15x=90 - 5=>
=> 15x =85= x= 5.6666...
<u>Answer:</u>
The correct answer option is C. 13.6 units.
<u>Step-by-step explanation:</u>
Line segment AB was dilated to create the line segment A'B' using the dilation rule 
.
We are to find the value of 
which is the distance between the twp points A and A'.
For this, we will divide the distance of A'Q by the dilation factor and then subtract the given length.
x = 
= 13.6 units
Answer:
r ≈ 2.07
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r= C/2π = 13/2π ≈ 2.06901
Answer:
c. (A + B)^2-A^2 + 2AB + B^2
Step-by-step explanation:
Given that:
a.
(A-B)^2 = A^2 - 2AB + B^2
If and only if AB = BA
Then;
(A-B)^2 = (A -B ) (A - B)
(A-B)^2 = A^2 - AB-BA + B^2 (FALSE)
b.
(AB)^2=A^2B^2
on true if any only if AB =BA
(AB)^2= (AB) (AB)
c.
(A+ B)^2 = A^2 + 2AB + B^2
(A+ B)^2 = (A + B) (A+B)
(A+ B)² = A × A + A × B + B × A + B × B
(A+ B)^2 = A^2 + A*B + B*A + B^2
This is true
