Answer:
1. 3) measure of angle 3 and measure of angle 5 are supplementary
2. x=16
Answer:
x= 14
Step-by-step explanation:
sqrt( x-5) = x-11
Square each side
(sqrt( x-5))^2 = (x-11)^2
x-5 = x^2 - 22x +121
Subtract (x-5) from each side
x-5-x+5 = x^2 -22x +121 -x+5
0 = x^2 -23x +126
Factor
0 = ( x-14) ( x-9)
Using the zero product property
x-14 = 0 x-9=0
x=14 x=9
Check the solutions
sqrt( x-5) = x-11
sqrt( 14-5) = 14-11
sqrt(9) = 3
3=3
solution
sqrt( x-5) = x-11
sqrt(9-5) = 9-11
sqrt(4) =-2
2 = -2
not a solution
Answer:
x = 6
Step-by-step explanation:
CT is a median, which means it divided AB into two equal parts so we can write the following equation:
7x + 9 = 5x + 21 transfer like terms to the same side of the equation
7x - 5x = 21 - 9 do the extraction
2x = 12 divide both sides by 2
<u>x = 6</u>
Answer:
3(x - 4)(x + 4)
Step-by-step explanation:
Answer:
19
Step-by-step explanation:
If you want to find the answer of the equation, sub the given information into it:
z + xz + y
we know that:
x = 5
y = 1
z = 3
We got:
= 3 + 5*3 + 1
= 3 + 15 + 1
= 19
Hope this helped :3
