s = 3
Answer:
Step-by-step explanation:
- Estimated height is 4 feet
- Measured height is 4 feet 2 inches
1. The measurement is actual and should be considered as such. Estimate is approximate most of the time.
2. <u>The error is:</u>
- 4 feet 2 inches - 4 feet = 2 inches
3. <u>Percent error:</u>
- 2 inches/4 feet 2 inches × 100% =
- 2 inches / 50 inches × 100% =
- 0.04× 100% =
- 4%
Start by taking the information we know, and write equations to represent the realationships:
1) "1/8 lbs less flour to make bread than to make cookies"

2) "1/4 lb more flour to make cookies than to make brownies:

3) "she used 1/2 lb of flour ro make bread"

From here you can solve for

using back substitution.
Answer:
f(x) × g(x) = 15x^6 - 6x^4
Step-by-step explanation:
hello :
f(x) = 5x^3 -2x and g(x) =3x^3.
f(x) × g(x) = 3x^3(5x^3 -2x) = 15x^6 - 6x^4
