Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
g(x) = -x + 2
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in function values: (f + g)(x) = x + 3 - x + 2
- [Subtraction] Combine like terms (x): (f + g)(x) = 3 + 2
- Add: (f + g)(x) = 5
<span>A rectangle has two pairs of sides of equal length. </span>
<span>So perimeter P = 2ft + 18in + 2ft + 18in </span>
<span>The units have to be all the same to add them so.... </span>
<span>P = 2ft + 1.5ft + 2ft + 1.5 ft </span>
<span>P = 7 ft. </span>
<span>So the board would have to be 7 feet to make a 2ft x 1.5ft picture frame.</span>

Answer:
<em>It can also be expressed as 35/14.</em>
Step-by-step explanation:
<u>Equivalent Ratio</u>
A ratio is a relation between two numbers a, b in the format a:b and it's equivalent to the division a/b.
Since it's equivalent to a division or a fraction, it can be simplified or amplified by multiplying or dividing both sides by the same number.
The ratio 5:2 can be amplified by multiplied by 7 as follows:
5*7:2*7 = 35:14.
It can also be expressed as 35/14.
