Answer:

The height of the parallelogram is 3 yards.

Step-by-step explanation:

A parallelogram has a base of 7 yards, and an area of 21 square yards.

The formula for the area of a parallelogram is A = bh.

So, to find h (the height), that formula becomes h = A/b

h = 21/7

h = 3

The height of the parallelogram is 3 yards.

(Work Check:

A = bh

A = 7 * 3

A = 21)

How do I convert 75 feet/second to miles/hour rounding to the nearest whole number
MAVERICK [17]

Answer:

51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

Step-by-step explanation:

Given:

75 feet/second.

Now, to convert 75 feet/second into miles/hour.

So, to convert we divide the value of feet per second by conversion factor to get miles per hour.

Value of feet per second = 75.

Conversion factor = 1.4667.

Now, putting the formula to get the value in miles/hour:

Value in miles/hour = value of feet/second ÷ conversion factor.

Value in miles/hour = 75\div 1.4667.

                                 = 51.135\ miles/hour.

<em>Rounding nearest to whole number = 51 miles/hour.</em>

Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

Simplify (a+b)^3 + (a-b)^3 + 6a(a^2-b^2)
11111nata11111 [884]

Answer:

8a^3.

Step-by-step explanation:

(a+b)^3=a^3+b^3+3a^2b+3ab^2

(a-b)^3=a^3-b^3-3a^2b+3ab^2

(a+b)^3+(a-b)^3=2a^3+6ab^2

According to the question

(a+b)^3+(a-b)^3+6a(a^2-b^2)

Put in the value

=2a^3+6ab^2 +6a^3–6ab^2

=8a^3
