Answer:
m∠ABC = 45°
Step-by-step explanation:
See the attached figure.
As shown in the figure
Line C B extends through point D to form the exterior angle that is 135 degrees.
So, m∠ABD = 135°
But m∠ABC + m∠ABD = 180°
∴m∠ABC = 180° - m∠ABD = 180° - 135°= 45°
Also, we should know that
m∠ABD = m∠BAC + m∠ACB
So, m∠ACB = 135° - 75° = 60°
========================================
<u>Very important note:</u>
If we replaced the location of B and C
SO, m∠ABC = 60° and m∠ACB = 45°
=========================================
Answer:
x² + 6ax + 4bx + 5a² - 5b²
Step-by-step explanation:
(x+5a+5b )(x+a-b)
x² +a x -bx +5ax + 5a² -5ab + 5bx + 5ab -5b²
x² + 6ax + 4bx + 5a² - 5b²
A quadratic function is a function whose highest power for the variable is 2.
h(x) = 3x(x - 2) - 4 = 3x^2 - 6x - 4 is a quadratic function.
Hey there!
ANSWER: 
EXPLANATION:
To find the answer to your question, you will need to add.

First, multiply the denominator.

So the denominator will be 20.
Now move on to the numerator. Multiply 5 by 3.

Now multiply 4 bu 2.

If you want to get the numerator, add what you got after multiply.

The numerator is 23. So now let's complete the fraction.

This is your answer!
Hope this helps!
