Two square sheets of cardboard used for making book covers differ in area by 64 square inches. An edge of the larger square is 2
photoshop1234 [79]

Answer:

15 inches

Step-by-step explanation:

We assume that the edge of the small square is x (inches).

As the edge of the larger square is 2 inches greater than that of the smaller one, so that the edge of the larger square = edge of the small square  + 2 = x + 2 (inches)

The equation to calculate the are of a square is: <em>Area = Edge^2 </em>

So that:

+) The area of the larger square is: <em>Area large square = </em>(x+2)^{2}<em> (square inches)</em>

+) The area of the smaller square is: <em>Area small square = </em>x^{2}<em>(square inches)</em>

<em />

As difference in area of both squares are 64 square inches, so that we have:

<em>Area large square - Area small square  = 64 (square inches)</em>

<em>=> </em>(x+2)^{2} -x^{2} =64<em />

<em>=>  </em>x^{2}+4x+4  -x^{2} =64<em />

<em>=> 4x + 4 = 64</em>

<em>=> 4x = 64 - 4 = 60 </em>

<em>=> x = 60/4 = 15 (inches)</em>

So the length of an edge of the smaller square is 15 inches

A train has 6 identical passenger cars that are each 18 m long.
Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m

Answer:

The answer is 6ab³c(3ab + 4c)

Step-by-step explanation:

You have to collect the like-term :

18a²b⁴c + 24ab³c²

= 6(3a²b⁴c + 4ab³c²)

= 6a(3ab⁴c + 4b³c²)

= 6ab³(3abc + 4c²)

= 6ab³c(3ab + 4c)

Sara paid $11.88 total for apples, after a 3 dollar coupon, and $7.58 for berries with a $20 bill. How much change did Sara rece
Nataliya [291]

After the discount, Sara received a change of <u>$3.54</u>.

Define discount.

The discount is <u>determined by dividing the purchase price by the item's par value</u>. Discount is the type of original price reduction or a new lower price for a product. In other words, a discount i<u>s a sum of money or a portion of the regular selling price of anything</u>.

Given that a discount is the price reduction of goods or services that store owners give at the advertised price, it can be computed using the formula <u>Discount = List Price - Selling Price.</u>

Solution Explained:

Given,
Price of apples = $11.88, price of berries = $7.58

The discount on the coupon is $3 and she paid with a $20 bill

So, total cost = 11.88 + 7.58 = 19.46

Applying discount on the cost =  19.46 - 3 = 16.46

The total change Sara gets is = 20 - 16.46 = $3.54

Therefore, Sara receives a change of $3.54
