Answer:

20km = 6.5km + w

w = 20 km - 6.5 km

w = 13.5 km

Step-by-step explanation:

because  20km  =  present week

last week = w

The sentence says  [Present Week] = 6.5 km  MORE than [Last Week]

MORE mean "+"

[Present Week] = 6.5 km +  [Last Week]

20 = 6.5 km + [Last Week]

20 = 6.5 + w

w = 20 - 6.5 = 13.5 km

Multiply and Simplify<br> (x-4)(x^2 - 5x - 6)
kirill [66]

Answer:

x^3 -9x^2 +14x +24

Step-by-step explanation:

(x-4)(x^2 - 5x - 6)

Multiply the x by everything in the second term

x * (x^2 - 5x - 6)

x^3 -5x^2 -6x

Multiply the -4 by everything in the second term

-4 * (x^2 - 5x - 6)

-4x^2 +20x +24

Add everything together

I like to line them up vertically

x^3 -5x^2 -6x

      -4x^2 +20x +24

-------------------------------

x^3 -9x^2 +14x +24

Find the area of a semicircle
Furkat [3]

Answer:

18pi, or 56.52

Step-by-step explanation:

To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle

However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:

(pi x radius^2)/2 = area of semi-circle

(pi x 6^2)/2 = area of semi-circle

(36 x pi)/2 = area of semi-circle

18 x pi = area of semi-circle

18 x 3.14 = area of semi-circle

56.52 = area of semi-circle
