x3 − 4x2 + 3x + 7 divided by (x + 5)
I'm studying for a quiz but I don't understand how to do this.
Please explain. Brainliest only will be given if it includes an explanation.
I will report you if you give some random answer just for the points, don't test me.

Step-by-step explanation:

x³ - 4x² + 3x + 7

= (x + 5)(Ax² + Bx + C) + D

= Ax³ + (B + 5A)x²+ (C + 5B)x + (D + 5C).

By Comparing Coefficients, we have

A = 1

B + 5A = -4

C + 5B = 3

D + 5C = 7

Solving them, we have A = 1, B = -9, C = 48 and D = -233.

Hence x³ - 4x² + 3x + 7 = (x + 5)(x² - 9x + 48) - 233.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
