1- $8x^2+12x \\ =4x*2x+4x*3 \\ =4x(2x+3) \\ =A$

2- $20mn-30m \\ =10m*2n-10m*3 \\ =10m(2n-3) \\ =B$

3- $15x^3-12x \\ =3x*5x^2-3x*4 \\ =3x(5x^2-4) \\ =B$

4- $12x^2y-3x^2y^2-15xy \\ =3xy*4x-3xy*xy-3xy*5 \\ =3xy(4x-xy-5) \\ =C$

5- $24w^2x^6-8wx^3 \\=8wx^3*3wx^3-8wx^3*1 \\ =8wx^3(3wx^3-1) \\ =D$

B. A 50A by 35ft residential

MariettaO [177]

Answer:

1.13 food per square feet

Step-by-step explanation:

Given

Dimension: 50ft by 35ft

Servings = 1975

Required

Determine the amount per servings

First, we calculate the area.

$Area = 50ft * 35ft$

$Area = 1750ft^2$

Next, we calculate the amount per square foot.

This is:

$Rate = \frac{Serivings}{Area}$

This gives;

$Rate = \frac{1975}{1750}$

$Rate = 1.13$

Answer: x = 2

Step-by-step explanation:

$2^{2x}-2^x-12=0\\\\\text{Let u = }2^x\\\\u^2-u-12=0\\(u-4)(u+3)=0\\\\u-4=0\quad and\quad u+3=0\\u=4\qquad and\quad u=-3\\\\\text{Substitute u with }2^x\\2^x=4\qquad and \quad 2^x=-3\\2^x=2^2\quad and\quad \text{not possible}\\\boxed{x=2}$
