A scale drawing of a field is shown below. The drawing uses a scale of 1 in. = 14 ft. What is the area of the actual field?
svp [43]

Answer:

D. 4,704 ft²

Step-by-step explanation:

Giving a scale of 1 in. = 14 ft, to find the actual area of the field represented by the triangular drawing above, convert the length of the base and height to the actual lengths of the field using the scale.

Height of drawing = 8 in.

Actual height = 8*14 = 112 ft

Base of drawing = 6 in.

Actual base = 6*14 = 84 ft

Area of the field = area of ∆

Area = ½*base*height

Area = ½*84*112

Area = 4,704 ft²

I WILL MARK BRAINLIEST PLEASE HELP !! Determine whether the two triangles are similar.
soldi70 [24.7K]

The two triangles are similar by SSA similarity. Option B is correct.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.

From the triangle ABC and DEC

The ratio of the sides is;

\rm  \frac{10}{12}= \frac{8}{9.6} \\\\ \frac{5}{6}= \frac{5}{6}

One angle c is common in the two triangles.

The two triangles are similar by SSA similarity.

Hence, option B is correct.

To learn more about the triangle, refer to:

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!
kvv77 [185]

Answer:

Answer: Third option is the right answer.

Step-by-step explanation:

First we the write the expression

(a+b)(a^{2}+b^{2}-ab)

Now teacher says that the product of these polynomials will result in the sum of  a^{3}+b^{3}

Now the teacher ask if we put the value of a = 2x and b = 1 then what will be the expression look like.

(2x+1)\left [ (2x)^{2}+(1^{2})-(2x)(1)\right ]

=(2x+1)(4x^{2}+1-2x)

So third option is looking like our expression.
