Answer:

1 centimeter = 40 kilometers

? centimeter = 440 kilometers

The simple way to do this is to set it as a ratio as shown above. From 40 to 440, there is a increase in 11 times. (40 x 11 = 440)

So, you would do 1 x 11 = 11. This means 11 centimeters is equal to 440 kilometers.

11 centimeter = 440 kilometers

One inch equals 25 miles
Two inches equals fifty miles
Three inches equals seventy five miles
Four inches equals one hundred miles

.1 inches equals 2.5 miles
.4 inches equals 10 miles

Seventy five miles plus ten miles equals eighty five miles.

Given the function h(x) = x2 – 7x + 6, determine the average rate of change of

guapka [62]

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(h(7) - (h(3)) / (7 - 3)

h(7) = 7² - 7×7 + 6 = 49 - 49 + 6 = 6

h(3) = 3² - 7×3 + 6 = 9 - 21 + 6 = -6

7 - 3 = 4

(6 - -6)/4 = 12/4 = 3

the average change rate in that interval is 3 (or fully 3/1).

Answer:

a - b2

Step-by-step explanation:

STEP 1 :

Trying to factor as a Difference of Squares:

1.1 Factoring: a-b2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : a1 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares

Final result :

a - b2

HOPE THIS HELPS!

PLEASE MARK BRAINLIEST! :)
