Please help me solve (x+3) (x+7)

vodka [1.7K]

Step-by-step explanation:

Here, we'll need to multiply these two values together. I'll use the expansion formula, which goes as follows:

$(a+b)(c+d)$

Expand

$ac + ad + bc + bd$

Lets apply this to the following equation:

$(x+3) (x+7)$

Expand.

$(x*x) + (x * 7) + (3 * x) + (3 * 7)$

Simplify.

$(x^2) + (7x) + (3x) + (21)$

Remove parenthesis and add.

$x^2+10x+21$

Answer:

x^2+10x+21

Answers; A) 135 degree’s B) 30 Degree’s C) 180 or 0 Degree’s D) 90 Degree’s

Vladimir [108]

Answer:

C). 0 degrees

Step-by-step explanation:

The given equation is:

-4 + 6 sinx = -4 + 4 sinx

adding 4 on both sides:

4 - 4 + 6 sinx = 4 - 4 + 4 sinx

6sinx = 4sinx

dividing by 2 on both sides, we get:

6sinx/2 = 4sinx/2

3 sinx = 2 sinx

subtracting 2 sinx from both sides we get:

sin x = 0

x = sin⁻¹ (0)

x = 0 degrees

Apples cost $3.60 for 3 lb. At that rate, how many pounds of apples can you buy for $8.40?

irinina [24]

Apples cost $3.60 for 3 pounds . The rate can be calculated as follows

$\begin{gathered} 3\text{ pounds = \$3.60} \\ 1\text{ pounds = ?} \\ \text{rate = }\frac{3.60}{3} \\ \text{rate}=\text{ \$1.2 per pound} \end{gathered}$

The amount of pounds you can buy for $8.40 can be computed below

$\begin{gathered} \text{rate}=\frac{8.40}{\text{pounds}} \\ 1.2=\frac{8.40}{\text{pounds}} \\ weight\text{ in pounds = }\frac{8.40}{1.2} \\ \text{weight in pounds = 7 Ib} \end{gathered}$
