What is the area of the triangle?

Answers

Answer:

0.18ft.

Step-by-step explanation:

Points (4, 5) and (10, 5) are vertices of a rectangle.

The length of the rectangle is twice the width.

The other vertices are located at (4, ___ ) and (10, ___ ). What could these ordered pairs be?

pls help im begging yu

Answers

Answer:

the remaining two vertices must be (4, -7) and (10, -7).

Step-by-step explanation:

The vertices (4, 5) and (10, 5) lie on the same horizontal line, y = 5. The length of the rectangle is the difference between the two x-coordinates: 10 - 4, or 6.

Let's denote 6 as the width. Then the length is twice that, or 12.

Then the remaining two vertices must be (4, -7) and (10, -7).

Check: is the width 6? Does 10 - 4 equal 6? Yes

Is the length twice the width, or 12? Does 5 - (-7) = 12? YES

The other vertices are located at (4, -7 ) and (10, -7)

Area of a rectangle

Given two points on a rectangle as (4, 5) and (10, 5)

Since both coordinates lies on the same y axis, then the width of the triangle is expressed as;

width = 2(10-4)

width = 12 units

The y coordinate of the other vertices will be;

y = 5 - 12

y = -7

Hence the other vertices are located at (4, -7 ) and (10, -7)

Answer:

it is 3

Step-by-step explanation:

cause 3 is the highest exponent value

Answer:

The degree of this polynomial is 3.

Step-by-step explanation:

Hey!

==================================================================

When a polynomial has more than one variable, we need to look at each term to find out what the degree is. Terms are separated by + or - signs.

Find the degree by adding the exponents of each variable in it,

The largest such degree is the degree of the polynomial.

Let's start out by finding the degrees for each terms:

3x³ = The degree, or exponent, of x is 3.

5x² = The degree, or exponent, of x is 2.

1 = Constant Terms do not have a degree.

So, since the largest degree of a term is the degree of the polynomial., The degree of this polynomial is 3, since that is the highest!

What is the value of x?

Answers

Answer:

x = 6/2 = 3

Step-by-step explanation:

This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.

The scale factor is how much the enlargement is.

The side of Figure A is 2.

So we must multiply 2 ⋅ 1 1/2.

2 ⋅ 1 1/2 (3/2) = 6/2

6/2 is equal to 3.

Therefore, the value of x in Figure B is 3.
