Answer:

Step-by-step explanation:

Make both a single fraction by adding together.



Simplify


Answer:
She paid $29.29
Step-by-step explanation:
Finding 7% of 25
Y is 7% of 23.2
Solving our equation for Y
Y = P% * X
Y = 7% * 23.2
Converting percent to decimal:
p = 7%/100 = 0.07
Y = 0.07 * 23.2=1.624
Y ≅ 1.62
Finding 18% of 25
Y is 18% of 23.2
Solving our equation for Y
Y = P% * X
Y = 18% * 23.2
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 23.2= 4.176
Y≅4.18
Add sales tax and tip to 25
25+4.18+1.62= 30.8
But since my answers were estimated to a different way, I would say it s best to say it is d.29.29

<em><u>Solution:</u></em>
Given that we have to multiply the polynomials

Multiplying polynomials is similar to multiplying numbers
When you multiply two terms together you must multiply the coefficient (numbers) and add the exponents
Let us multiply the given polynomials

Multiply each term in first bracket with each term in second bracket

Add the exponents and multiply the coefficients

Combine the like terms -30x and 48x

Combine the like terms 

Thus the polynomials has been multiplied
