Answer:
1. C. 4x + 40
2. a. - 2a + 10
3. d. 13x - 45
4. 2c-7d
5. b. -2z - 12
Step-by-step explanation:
1. 4(x+10) = 4x+4*10 = 4x+40
C
2. -2(a - 5) = -2*a -2*-5 = -2a+10
A
3. 10x + 3 (x-15)
10x + 3x -3*15
10x+3x-45
13x-45
D
4. -5(c+d) + 7c - 2d
-5c-5d + 7c-2d
-5c+7c -5d -2d
2c-7d
5. 2(2z + 4) - 2 (3z + 10)
2*2z +2*4 -2 *3z -2*10
4z+8 -6z-20
4z-6z+8-20
-2z-12
B
Answer:
B) 5
Step-by-step explanation:
f(-2) = (-2)² + 5•(-2) +11
f(-2) = 4 -10 +11
f(-2) = 5

Answer:
Knowing what x equals helps you completely solve the equation, because wherever theres an x, you can replace with a 6. So once you do the equation i did below, you can figure out that 47 is not greater than 47.
Step-by-step explanation:
7(6) + 5 = 2(6) + 35
42 + 5 = 12 + 35
47 = 47
Therfore knowing what x equals helps you solve the equation.
