Answer:
B and B' are both 72 degrees, and sides BC and B'C' are both 5 units long.
Step-by-step explanation:
Parallelogram ABCD is reflected over the x-axis. What rule shows the input and output of the reflection, and what is the new coordinate of A'? Triangle ABC has been translated to create triangle A'B'C'. Angles C and C' are both 32 degrees, angles B and B' are both 72 degrees, and sides BC and B'C' are both 5 units long.
We can write x=-5 and x=2 so that they are both equal to 0
x+5=0 and x-2=0
How we can multiply x+5 and x-2 and set them both equal to 0
(x+5)(x-2)=0
Then you distribute to find the equation
x^2-2x+5x-10=0
or
x^2+3x-10=0

Answer:
She would only need to add half (1/2) a cup of flour.
Step-by-step explanation:
Think of it as when you are counting quarters. They go by 1/4's. So, let's say you need 75 cents ( 3/4 ), but you only have 25 cents ( 1/4 ). You would need 50 cents (1/2) to be able to have 75 cents!
Hope this helps you out!!! (:
