Answer:
B
Step-by-step explanation:
So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.
Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.
Heres what we know however:
angle 1 + angle 2 = 180 degrees.
How do we know this?
Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.
Lets input that into our nice lil equation to get an answer:
7 degrees+angle 2 = 180 degrees
Now lets solve.
Subtract 7 on both sides, and your left with:
angle 2 = 173 degrees.
So the answer must be:
<u>173 degrees</u>
Hope this helps! ;)

Answer:
![49x^2+126xy+81y^2](https://tex.z-dn.net/?f=49x%5E2%2B126xy%2B81y%5E2)
Step-by-step explanation:
Use the square of a binomial theorem
= ![a^2+2ab+b^2](https://tex.z-dn.net/?f=a%5E2%2B2ab%2Bb%5E2)
Now expand the given equation:
![(7x+9y)^2=49x^2+126xy+81y^2](https://tex.z-dn.net/?f=%287x%2B9y%29%5E2%3D49x%5E2%2B126xy%2B81y%5E2)
Hope this helps :)
Have a great day!

Answer:
2x² +5x -12 = 0
Step-by-step explanation:
When p and q are roots of a quadratic, its factored form can be written as ...
(x -p)(x -q) = 0
Here, the roots are given as -4 and 3/2, so the factored form would be ...
(x -(-4))(x -(3/2) = 0
Multiplying by 2 gives us ...
(x +4)(2x -3) = 0
Expanding the product, we find the desired quadratic is ...
2x² +5x -12 = 0
