A binomial squared is written like

$x^2+2ax+a^2$

So, we have $2a=6 \iff a=3$

So, we want to complete the square $(x+3)^2 = x^2+6x+9$

We can add and subtract 9 to write

$x^2+6x = x^2+6x+(9-9) = (x^2+6x+9)-9 = (x+3)^2-9$

Pierre is running 26 and 2/10 miles in the marathon. He has run 3/4 of the way. How far has he run?

Harman [31]

Pierre ran 19 and 13/20 miles.

Given:
marathon length : 26 2/10 miles
pierre's length ran : 3/4 of the way.

Multiply the fractions.
Convert the marathon length from a mixed fraction into a fraction.
26 2/10 = ((26*10)+2)/10 = (260+2)/10 = 262/10

262/10 * 3/4 = (262*3) / (10*4) = 786/40 = 19 26/40

19 26/40 simplified to 19 13/20 miles

26 ÷ 2 = 13
40 ÷ 2 = 20

Find the surface area of a cylinder with a base diameter of 4 in and a height of 3 in . Write your answer in terms of π , and be

marissa [1.9K]

Find Radius:

Radius = Diameter ÷ 2

Radius = 4 ÷ 2 = 2 in

Find Surface Area:

Surface Area = 2πr² + 2πrh

Surface Area = 2π(2)² + 2π(2)(3)

Surface Area = 8π + 12π

Surface Area = 20π in²

Answer: 20π in²
