<u><em>Answer: x=8</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract by 10 from both sides of an equation.
x+10-10=18-10
simplify
18-10=8
<u><em>x=8</em></u>
Hope this helps!
Thanks!
Have a great day!

Answer:
3. 4a(a + 1) - 15
step-by-step explanation:
1. (x +y)² + 11 (x + y) + 30
= x + y {(x +y) + 11} + 30
2. (a - b)² - 16(a - b) + 60
= (a - b){(a - b) - 16} + 60
3. 4a² + 4a - 15) - 15
4. 2x² + 5x + 2
= x(2x + 5) + 2
1) Point-slope form
(y-y1)=m(x-x1)
m= - 3,
point (3,-4), so x1 = 3, y1 = - 4.
(y+4)= -3(x- 3)
2)Point-slope form
(y-y1)=m(x-x1)
m= - 3/4,
point (4,5), so x1 = 4, y1 = 5.
(y-5)= - 3/4(x-4)
Answer:
(x+1)(x-5)
Step-by-step explanation:
(x+a)(x+b)=x²-4x-5
then a+b=-4 and a*b=-5
so a=-1 and b=5
