Liliana solved the equation below. When she tried to verify her answer, she realized she made an error. One-third (x + 18) = 7 One-third x + 6 = 7 One-third x + 6 minus 6 = 7 + 6 One-third x = 1 x = 3 Which correction should Liliana make? The first step should be One-third x + 54 = 7. The second step should be One-third x + 6 minus 6 = 7 minus 6. The third step should be One-third x = 13. The final step should be x = one-third.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

c-   36
