Solve. (x-4)=5PLEASE HELP

Answers

Answer 1

Answer:

A

Step-by-step explanation:

(x-4)^2=5

(x-4)(x-4)=5

x(x-4)-4(x-4)=5

distribute

x^2-4x-4x+16=5

combine like terms

x^2-8x+16=5

move terms to the left and combine

x^2-8x+11=0

use the quadratic formula and simplify

x=-(-8)+/-2 to the square roots of 5 over 2

separate and solve

x=4+ square root of 5

x=4- square root of 5

ANSWER: x=4+/- square root of 5

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.

Answers

Answer:

depends on the other side, so... maybe

Step-by-step explanation:

If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.

Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25.  If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25

The length of Kathy's rectangular
garden is 4 feet more than the width. If
the perimeter of her garden is 40 feet,
what is the length of Kathy's garden?

Answers

Half the perimeter is the length + the width.

Let the width = x

The length is x + 4. ( 4 feet more than the width)

Now you have x + x + 4 = 20

Combine like terms:

2x + 4 = 20

Subtract 4 from both sides:

2x = 16

Divide both sides by 2:

X = 8

The width is 8 feet

The length is 8 + 4 = 12 feet

Use similar triangles and a proportion to find the length of the lake shown here.
(Hint: The side 92 m long in the smaller triangle corresponds to side of 92 m + 112 m = 204 m in the larger triangle.)
N= m

Answers

Answer: n = 152 m

Step-by-step explanation:

write a proportion to find n.

46/n = 92/204

n = 102 m

The length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

What is similar triangle's proportion property?

In the two similar triangle, the ratio of two sides of one triangle is equal to the ratio of corresponding sides of the other triangle.

In the figure shown,

The length of the base of the smaller triangle is 92 meters, The height of this triangle is 46 meters.

The total length of the base of the larger triangle is,

[tex]112+92=204\rm\; m[/tex]

The height of this triangle is n meters, which is equal to the length of lack. Thus, by the similar triangle proportion property,

[tex]\dfrac{n}{204}=\dfrac{46}{92}\\n=\dfrac{46\times204}{92}\\n=120\rm\; meters[/tex]

Thus, the length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

At the grocery store, 6 pints of ice cream cost $14.40. How much would 40 pints of ice cream cost?

Answers

Answer:

$96

Step-by-step explanation:

14.40 / 6 = $2.40

$2.40 x 40 =

$96

Hope that helps!

The solution is $ 96

The cost of 40 pints of ice cream is given by the equation A = $ 96

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 40 pints of ice cream be A

Now , the equation will be

The cost of 6 pints of ice cream = $ 14.40

So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6

Substituting the values in the equation , we get

The cost of 1 pint of ice cream = 14.40 / 6

The cost of 1 pint of ice cream = $ 2.40

Now ,

The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream

Substituting the values in the equation , we get

The cost of 40 pints of ice cream A = 40 x 2.40

The cost of 40 pints of ice cream A = $ 96

Therefore , the value of A is $ 96

Hence , the cost is $ 96

At Norman's Newsstand, 5 magazines cost $20.00. How many magazines could you buy with $44.00?

Answers

Answer: 11 magazines

Step-by-step explanation:

1)     20/5 = $4 per magazine

2)     44/4 = 11 magazines

Answer:

10 magazines

Step-by-step explanation:

5 magazines cost $20.00

You have $44.00

If 5 magazines cost $20.00

Then 10 magazines would cost $40.00

Since the maximum amount of money you can spend is $44.00, you can only buy 10 magazines for $40.00 and be left with $4.00.
