14.50 times 0.20 = 2.9
He would give a $2.90 as a tip of 20% from a bill of $14.50
Given:
Polynomial is
.
To find:
The sum of given polynomial and the square of the binomial (x-8) as a polynomial in standard form.
Solution:
The sum of given polynomial and the square of the binomial (x-8) is

![[\because (a-b)^2=a^2-2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2%5D)

On combining like terms, we get


Therefore, the sum of given polynomial and the square of the binomial (x-8) as a polynomial in standard form is
.
Answer:
IIaI-IbII
Step-by-step explanation:
II-30I-I-5II=
I30-5I=
I25I=
25
II-5I-I-30II=
I5-30I=
I-25I=
25
Answer:
d) 87
Step-by-step explanation:
to solve this lets set up the equation

then we multiply 4 on both sides
253+x=340
and subtract 253 on both sides
x=87
to double check take the averages
(87+85+70+98)/4=85
