Answer:
x=2
Step-by-step explanation:
2 times x + 4 = 8
-4 -4
2 times x = 4
/2 /2
x = 2
Answer:
y =24
Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles
y+18 + 3y -41 = y+49
Combine like terms
4y -23 = y+49
Subtract y from each side
4y -y -23 = y+49-y
3y -23 = 49
Add 23 to each side
3y -23+23 = 49 +23
3y = 72
Divide by 3
3y/3 = 72/3
y =24
14 + 12 = 26
26 + 10 = 36
36 + 8 = 44
44 + 6 = 50
(notice the pattern)
14, 26, 36, 44, 50
Answer:
x=-2 or x=7
Step-by-step explanation:
X²-5X-14=0 find the factors of -14x² which is -7x and +2x
X² -7x + 2x - 14 = 0 factorize
x(x-7) + 2(x-7) = 0
(x+2)(x-7) =0
x+2 = 0 or x-7= 0
x=-2 or x=7
