10 students were asked because there was 10 answers given.
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:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached images below, to find more information about the graph
The equation is:
f(x) = x^4 – 2x^3 + 5x^2 – 7x + 9
The equation has only complex roots.
The price of the chair afterwards was $176.40. You take $210 and multiply it by .40 and get $84. Then you subtract it from 210 and get 126. Then take 126 multiply it by .40 and get $50.40 then you add it back to the $126 and get $176.40
