Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
Step-by-step explanation:
Answer:
step 2
Step-by-step explanation:
took the test
No. Two angles will have to be the same and the third angle will just be 180° minus twice the smaller angles.
So if we let the equal angles equal a, and the large angle equal be we have:
2a+b=180
So there are infinitely many values that a and b can have.
a=(180-b)/2, so the smaller equal angles have the range (0,90)
b=180-2a, so the larger has a range of (0,180)
I night tutted i have you ever heard of the internet for a this week or two and you have to do
