-what is the sum of -15+18​

Answer:

Area = 6x + 36

Perimeter = 3x + 10

Step-by-step explanation:

Sides of the triangle:  12 ; (x - 7)  & (2x + 5)

Perimeter of the triangle = sum of all the sides

      = 12 + x - 7 + 2x + 5

      = 2x + x + 12 - 7 + 5     {Combine like terms}

      = 3x  + 10

Area of triangle:

Base = 12  & height = h = x +6

[tex]Area = \dfrac{1}{2}b*h\\\\=\dfrac{1}{2}*12*(x+6)\\\\[/tex]

= 6 *(x + 6)       {Use distributive property}

= 6*x + 6*6

= 6x + 36

Answer:

3.71 = (3.7 × 10)(1 × 10) = 3710.

Step-by-step explanation:

This fraction is alread reduced, We can't reduce it any further). As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 3710 is also equal to 3710 when expressed as a mixed number.

Answer:

Answer:

x = 6 for Side 14 - 2x

x = 9 for Side 2x + 1

x = 11 for Side 3x - 1

Step-by-step explanation:

14 - 2x + 2x + 1 + 3x - 1 = 26

-2x  + 2x + 3x - 1 + 1 + 14 = 26

3x + 14 + 1 - 1 = 26

3x + 14 = 26

    -14      -14

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

3x = 12

/3     /3

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

x = 4

Now, plug x = 4 into all the side expressions and find out their lengths.

14 - 2x

= 14 - 2(4)

= 14 - 8

= 6

2x + 1

= 2(4) + 1

= 8 + 1

= 9

3x - 1

= 3(4) - 1

= 12 - 1

= 11

Add all the lengths you got and you will see the perimeter is indeed 26, which means our side lengths are correct.

6 + 9 + 11 = 26

26 = 26 CORRECT

Step-by-step explanation:

Do 140/0.4=350

Answer:

350 apples

Step-by-step explanation:

a = total number of apples in the crate

a* 40% = number of red apples

a * .40 = 140

Divide each side by .40

a * .40/.40 = 140/.40

a =350

Answer: C. 16.4

Concept:

Here, we need to know the idea of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (-3, 4)

(x₂, y₂) = (7, -9)

Given expression

[tex]Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values into the expression

[tex]Distance =\sqrt{(7+3)^2+(-9-4)^2}[/tex]

Simplify value in the parentheses

[tex]Distance =\sqrt{(10)^2+(-13)^2}[/tex]

Simplify exponents

[tex]Distance =\sqrt{100+169}[/tex]

Simplify by addition

[tex]Distance =\sqrt{269}[/tex]

Convert square root to decimal and round the answer to the nearest tenth

[tex]\boxed{Distance=16.4}[/tex]

Hope this helps!! :)

We have that the distance around the park to the nearest yard,QM to the nearest yard and the Time of travel for man's jog is given respectively as

From the Question we are told that

[tex]PQ=(50-10)=40\\\\QR=(80-10)70[/tex]

Generally the equation for the Resultant PR is mathematically given as

[tex]PR=\sqrt{PQ^2+QR^2}\\\\PR=\sqrt{70^2+40^2}\\\\PR=80yd[/tex]

a)

Generally the equation for the Distance around they park is mathematically given as
