lions [1.4K]3 years ago
5 0

Answer:

13

Step-by-step explanation:

<em>1. Distribute each term in the first binomial to each term in the second binomial,</em> <em>FOIL (first, outer, inner, last)</em>

(3 - 2i) (3 + 2i)

9 + 6i - 6i - 4i^{2}

<em>2. Simplify </em>

9 - 4i^{2}

<em>3. Solve for i. </em>i^{2} = -1

9 - 4 (-1)

9 + 4 = 13

hope this helps!

oksano4ka [1.4K]

Answer:

\red{{7}^{15} }

Step-by-step explanation:

We know that,

{x}^{a}  \times  {x}^{b}  =  {x}^{a + b}  \\ ( {x}^{a} ) ^{b}  =  {x}^{ab}

Accordingly,

( {7}^{5} ) ^{3}  \\  {7}^{5 \times 3}  \\  {7}^{15}

What is the sum of 56+64 writen as the product of its gcf and another sum
jenyasd209 [6]
<span>Look for the sum of 56 and 64, written as the product of its GCF and another sum.
First, let’s find the greatest common factor of both given numbers:
=> 56 = 1, 2, 4, 7, 8, 13, 28 and 56
=> 64 = 1, 2, 4, 8, 16, 32, and 64
Now, we need to find the greatest common factor between the two numbers. The GCF of the 2 numbers is 8.
=> 56 / 8 = 7
=> 64 / 8 = 8
=> 56 + 64 = 120
=> (8 x 7) + (8 x 8)
=> 56 + 64
=> 120.</span><span>

Ln(x+7)=3<br> This is part of a webquest any help would be nice.
Assoli18 [71]

ln(x−7)==4/3

To solve for x, rewrite the equation using properties of logarithms.

e^ln(x−7) =e^4/3

Solve for x

x=e^4/3 + 7

The result can be shown in multiple forms.

Exact Form:

x= e^4/3+7

Decimal Form:

x=10.79366789
