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

What’s the answer to number 4 ?

Marizza181 [45]

Answer:

$4.36*10^-^1$

Step-by-step explanation:

Given:

$(3.6*10^-^2)+(4.0*10^-^1)$

Make the power of '10' equal by shifting the decimal place of any one value.

$(0.36*10^-^1)+(4.0*10^-^1)$

Taking the ' $10^-^1$ ' common

$10^-^1*(0.36+4.0)$

Adding the values in the bracket gives:

$4.36*10^-^1$
