Hope this helps :)

Answer 2

Answer:

7h - 15h + 40 = -72

-8h + 40 = -72

take +40 on the other side of equation

-8h = -72-40

-8h = -112

h = -112/-8

h = 14

3.1 Pull out like factors :

2y3 - 8y = 2y • (y2 - 4)

Trying to factor as a Difference of Squares:

3.2 Factoring: y2 - 4

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 : 4 is the square of 2

Check : y2 is the square of y1

Factorization is : (y + 2) • (y - 2)

Final result :

2y • (y + 2) • (y - 2)

Hey there! So because this is to many question rolled in one, Im only going to be answering your simplify questions.

Starting with

1: $(2)/(5) √(5)$
2: $44 √(7)$
3: $8 √(17)$
4: $2+2 √(3)$

So i solved this by using our square root functions. For if you didn't know, the square root symbol is this: √

The scale on a map is 1 in. = 0.5 mi. The distance between two towns on the map is 5.5 in. What is the actual distance between the two towns?6.25 miles
3.75 miles
2.75 miles
5.50 miles

Answers

In order to determine the actual distance between the two towns, multiply the distance between the two towns in the map, 5.5 in by the scale on the map. It is noted in the map that per inch distance corresponds to 0.5 mi. The product of 5.5 in and 0.5 mi/in is 2.75 miles. Thus, the actual distance between the towns is 2. 75 miles.

Answer:

Actual distance between 2 towns is:

2.75 miles

Step-by-step explanation:

The scale on a map is 1 inch = 0.5 miles

The distance between two towns on the map is 5.5 inch

1 inch= 0.5 miles

5.5 inch= 5.5×0.5 miles

= 2.75 miles

Hence, actual distance between two towns is:

2.75 miles
