Can you help stuck on this question for a while

Answer:

Option B

Step-by-step explanation:

Length of the rectangular sand box is given by the function,

F(x) = 3x³ + 6x - 2

Width of the sand box is represented by the function,

W(x) = 2x² - 4

Area function for the sand box will be,

Area of a rectangle = Length × Width

F(x) × W(x) = (3x³ + 6x - 2)(2x² - 4)

= 2x²(3x³ + 6x - 2) - 4(3x³ + 6x - 2)

= 6x⁵+ 12x³ - 4x²- 12x³- 24x + 8

= 6x⁵- 4x²- 24x + 8

Therefore, Area function will be represented by a polynomial degree of 5.

Option B will be the answer.

A mango weighs 36 ounces. The total weight of 3 magoes and 1 apple is the same as the weight of 5 apples. How much does 1 apple

Vadim26 [7]

Data:

M (mango)
A (apple)

We have:
1M = 36 ounces
3M + 1A = 5A

Replace and solving:

$3M + 1A = 5A$
$
3.(36) + 1A = 5A$
$108 + 1A = 5A$
$108 = 5A - 1A$
$108 = 4A$
$4A = 108$
$A = \frac{108}{4}$
$\boxed{A = 27}$

Answer:
Aple weigh 27 ounces
