The formula for the area of a triangle is Area=2(base)(height). Write an

Mathematics
1 answer:
NISA [10]2 years ago
7 0

Answer:

B

Step-by-step explanation:

area = 10x^2 + 20x

base = 20x

10x^2 + 20x = 0.5(20x)(height)

10x^2 + 20x = 10x(height)

(10x^2 + 20x) / 10x = height

\frac{10x^2 + 20x}{10x} = \frac{10x + 20}{10} = \frac{x + 2}{1} = x + 2

The answer is B

. In April, it rained 1/4 of an inch on 15 different days. How many inches of rain fell
notka56 [123]

Answer:

3.75, or \frac{15}{4} inches of rain during the 15 days of April.

Step-by-step explanation:

All you have to do is add \frac{1}{4} 15 times to get that number.

\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} = 3.75

You can also do 15 times \frac{1}{4}, which will result in the same thing.

(x-1)²-25=0<br> Factor by using the difference between two squares
Ronch [10]

Answer:

see explanation

Step-by-step explanation:

A difference of 2 squares factors in general as

a² - b² = (a - b)(a + b)

(x - 1)² - 25 ← is a difference of squares

with a = x - 1 and b = 5, thus

(x - 1)² - 25

=(x - 1 - 5)(x - 1 + 5) = (x - 6)(x + 4), then

(x - 6)(x + 4) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 4 = 0 ⇒ x = - 4

Solutions are x = - 4, x = 6

Which of the following angle measures are possible for a triangle to be classified as scalene? Select all that apply.
RUDIKE [14]

The angle measures that are possible for a triangle to be classified as scalene are:

  • 7∘,160∘,13∘
  • 48∘,71∘,61∘
  • 15∘,52∘,113∘

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

A scalene triangle  can be described as a  triangle  which consist three sides and all the three sides are of  different lengths, having  all three angles  with different measures.

It should be noted that  the sum of all the interior angles is  equal to 180 degrees.

In conclusion, scalene triangle serves as the  triangle having all three sides  to be in a  different lengths,  and the  three angles  have different measures.

The area of a rectangle is 56 cm. The length is 2 cm more than x and the width is 5 cm less than
Ira Lisetskai [31]

Answer:

<u>x = 6, length = 8 cm and width = 7 cm</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Area of a rectangle = 56 cm²

Length of the rectangle = x + 2

Width of the rectangle= 2x - 5

2. Solve for x. Round to the nearest whole number.

Area of a rectangle = Length * Width

(x + 2) (2x - 5) = 56

2x² + 4x - 5x  -10 = 56

2x² - x  - 66 = 0

Factoring, we have:

(2x + 11) * (x - 6) = 0

x₁ = 2x + 11 = 0 ⇒ 2x = -11;  x₁  = - 5.5

x₂ = x - 6 = 0 ⇒ x₂ = 6

We picked x₂ because x₁ will give us negative values for length and width.

Length = 6 + 2 = 8 cm

Width = 2 * 6 - 5 = 12 - 5 = 7 cm
