Step-by-step explanation:

Answer:

Length is 13 and width is 3

Step-by-step explanation:

First find an equation that represents this situation.

39 = w * (5w-2)

This works because 39 (the total area) is w (the width) times 5w - 2 (the length). So solve for w.

39 = w * (5w-2)

First, distribute the w over the terms in parentheses

39 = 5w^2 - 2w

Then, subtract (5w^2 - 2w) from both sides.

39 - 5w^2 - 2w = 0

Factor the left side of the equation:

(−5w−13)(w−3)=0

Then set each factor equal to zero.

−5w−13 = 0

Add 13 to both sides, then divide both sides by -5 to isolate w. This leaves you with w = -13/5

Then the other factor:

w−3 = 0

Add 3 to both sides. You're left with w = 3.

So w is either -13/5, or 3. And since the width can't be negative, it is 3.

Now to find the height, plug 3 into the equation we had from earlier:

39 = w * (5w-2)

Substitute w into the equation:

39 = (3) * (5(3)-2)

39 = 3 * (15 - 2)

39 = 3 * (13)

Because 3 * 13 is equal, 13 is the length.

Answer:

4|x|y²√(3yz)

She forgot the absolute value sign on x, and she left out the exponent on y.

Step-by-step explanation:

Step 1 is correct.

x may be positive, zero, or negative.

√x is always non-negative. To assure that √x² is non-negative, √x² = |x|.

√16 = 4

√3 = √3

√x² = |x|

√y² × √y² = √y^4 = y²

Since y² is always non-negative, there is no need for absolute value sign.

√y^4 = y²

Answer should be

4|x|y²√(3yz)

Answer:

sh.345

Step-by-step explanation:

The difference between the price selling with profit and price selling at a loss is 420-320 = 100

Profit is thrice the loss says we can take the difference in prices and divide it into 4 parts, x and 3x, representing the loss and thrice the loss, or profit margin.

x + 3x = 100

4x = 100

x = 25

loss would be 25,

profit would be 75

--------------------

sold at a profit: 420 -75 = sh.345

Does this exercise seem similar to what you're doing in class?

Answer:

2 km

Step-by-step explanation:

Reference angle = 45°

Opposite = u

Hypotenuse = 2√2 km

To find u, apply SOH:

Sin 45° = Opp/Hyp

Sin 45° = u/2√2

√2/2 = u/2√2 (sin 45 = √2/2)

Cross multiply

2*u = √2*2√2

2u = 4

Divide both sides by 2

u = 4/2

u = 2 km

An Example of a caravan is eight covered wagons traveling together on the trail. Meaning, option A is correct.

A caravan, travel trailer, camper, tourer, or camper trailer is a trailer towed behind a road vehicle to provide a more comfortable and secure sleeping space than a tent.

It allows people to have their own home on a trip or vacation without relying on a motel or hotel, and it allows them to stay in places where none are available. However, in some countries, campers are restricted to designated sites where fees must be paid.

Caravans range from basic models that are little more than a tent on wheels to those that have several rooms with all of the furniture, furnishings, and equipment of a home. The solid-wall trailers can be made of metal or fibreglass.

Answer:

11x + 10y

Step-by-step explanation:

The equation in the slope-intercept form is y = x + 3.8

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line that contains the points (–6.4, –2.6) and (5.2, 9).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

So, the equation,

y + 2.6 = {(9 + 2.6)/(5.2 + 6.4)} (x + 6.4)

y + 2.6 = x + 6.4

y = x + 6.4 - 2.6

y = x + 3.8

Therefore, the equation y = x + 3.8 is in the slope-intercept form.

On solving the question, we can say that y using the given information we can prove that similar angle m ∠ABC = m ∠EDC.

Polygons' corresponding sides and corresponding angles are compared as part of the geometric tests for congruence and similarity. With care taken to maintain the order of adjacency, each side and each angle in one polygon is paired with a side or angle in the other polygon in these tests.

Given:

m ∠1 = m ∠2

m ∠2 = m ∠4

We have to prove that m ∠ABC = m ∠EDC

∠EDC = ∠3 + ∠4

m ∠ABC = m ∠1 + m ∠2

m ∠EDC = m ∠3 + m ∠4

m ∠1 + m ∠2 = m ∠3 + m ∠4      

m ∠ABC = m ∠EDC

Hence, by using the given information we can prove that  

m ∠ABC = m ∠EDC.
