Answer:
4x³ + 14x² + 8x + 6
Step-by-step explanation:
Perimeter = 2(L + W) = 2(7x² + 4x + 3 + 2x³) = 14x² + 8x + 6 + 4x³
4x³ + 14x² + 8x + 6
Answer:
y = 4/3x - 10
Step-by-step explanation:
Slope: 4/3
y-intercept: -2 - (4/3)(6) = -2 - 8 = -10
Rewrite the percentage as a decimal:
8% = 8/100 = 0.08
Multiply the previous result by 24000:
24000*0.08 = $1920

Alice′s stamp collection➞75%x
75%x-40%×75%x+140=x-20%x
75%x-30%x+140=80%x
45%x+140=80%x
140=80%x-45%x
x=400
