Answer:

3x+15

Step-by-step explanation:

Given : The expression - 3(x+5)

To rewrite the expression using distributive property:

Solution :

Distributive property is multiplication distributes over the addition is a(x+y)=ax+ay

When we use the distributive property on the expression,

a=3 , x=x , y=5

Therefore, a(x+y)=ax+ay

\Rightarrow3(x+5)=3x+3(5)

\Rightarrow3(x+5)=3x+15

So, The answer is 3x+15

A rectangle has a perimeter of 84cm and a length 35cm what is its width
aleksandrvk [35]
P = 2(L + W)
P = 84
L = 35

now we sub
84 = 2(35 + W)
84 = 70 + 2W
84 - 70 = 2W
14 = 2W
14/2 = W
7 = W....so the width is 7 cm

Is this question proportional? why or why not

If j(x) = x4 - 81, and k(x) = x + 3 then j(x) k(x) =
Bad White [126]
Hi there!
The question here is asking us to multiply two functions together - j(x) and k(x). First, we need to determine the expressions for j(x) and k(x). Since this is given, we can move straight onto multiplying the two functions together, which will give us our answer.
j(x) × k(x)
Substitute expressions - 
(x⁴ - 81)(x + 3)
Simplify - 
(x⁴ - 81)(x + 3)
x⁵ + 3x⁴ - 81x - 243
Therefore, the answer is x⁵ + 3x⁴ - 81x - 243. Hope this helped!

g(x) = 3x - 2

<u>Step 2: Find g(1)</u>

  1. Substitute in <em>x</em>:                    g(1) = 3(1) - 2
  2. Multiply:                               g(1) = 3 - 2
  3. Subtract:                              g(1) = 1

<u>Step 3: Find f[g(1)]</u>

  1. Substitute in g(1):                    f[g(1)] = 2(1) + 1
  2. Multiply:                                   f[g(1)] = 2 + 1
  3. Add:                                         f[g(1)] = 3
