Perimeter of rectangle = all sides added
= 3+3+7+7 =20


volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5

What is the simplified form of the quantity of x plus 3, all over 4 + the quantity of x plus 2, all over 4 ? (2 points) the quan
pentagon [3]
ANSWER

\frac{2x + 5}{4}

EXPLANATION

We want to simplify

\frac{x + 3}{4} + \frac{x + 2}{4}

The fractions have the same denominator so we write one denominator and add the numerators to obtain,

\frac{x + 3 + x + 2}{4}

Regroup in the denominator to get,

\frac{x + x + 3 + 2}{4}

This simplifies to;

\frac{2x + 5}{4}

John Gray bought a basic car for $8,250.00, with options that cost $324.00. There's a 6% sales tax in his state and a combined $
Crank
Cost of the basic car bought by John Gray = $8250
Optional cost incurred after buying = $324
Total cost before tax = 8250 + 324
                                 = $8574 
Percentage of sales tax incurred = 6%
Amount of sales tax charged = (6/100) * 8574
                                               = $514.44
License and registration fees paid = $50
John's total cost = 8250 + 324 + 514.44 + 50
                          = 9138.44 dollars
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or option "A".
