Step-by-step Answer:
To prove
Triangle ADC is congruent to triangle BDC
AC=BC (given)
DC=DC (common)
AD=BD (given CD bisects AB)
Therefore triangle ACD is congruent to BDC (justification: SSS)
Answer:
A and B
Step-by-step explanation:
The 11 should be multiplied after 4 + x because the (4 + x) is the total amount of driveways she shoveled. If you solve for x using A's equation, you should get 9 as your answer. Therefore, your answer choices are A and B.
Answer:
Divide both sides by 3.
(x+2)^2=16
Square root both sides.
x+2= ± 4 (plus OR minus, can be either so we have to include both)
Minus 2 from both sides.
x=-2 ± 4
Add and minus the 4 to -2.
x = -2-4 = -6 and x=-2+4 = 2
