Answer:
531441
Step-by-step explanation:
4x + y = 23 and y = x + 8 means
4x + (x + 8) = 5x + 8 = 23 so
5x = 15 and x = 3
y = x + 8 = 3 + 8 = 11
Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
x = 25
Step-by-step explanation:
The top angle is the supplement of 3x - 10
180 - (3x - 10) = -3x + 190
The sum of the angles in a triangle is 180
(-3x + 190) + (25) + (x + 15) = 180
Combine like terms
-2x + 230 = 180
Subtract 230 from both sides
-2x = -50
Divide both sides by -2
x = 25
n, n + 2 - two consecutive even integers
2n = (n + 2) - 16
2n = n + 2 - 16
2n = n - 14 |subtract n from both sides
n = -14
n + 2 = -14 + 2 = -12
Answer: -14, -12.
