uhm!!! i need help please

Answer:

4x - 16

Step-by-step explanation:

A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

the perimeter of a triangle = sum of the side lengths

let the unknown length be represented with y

13x  - 21 = 4x + 3 + 5x - 8 + y

13x- 21 = 9x - 5 + y

Make y the subject of the formula

13x - 21 - 9x + 5 = y

4x - 16 = y

the side length = 4x - 16

Answer:

x = 114 ur welcome

Step-by-step explanation:

Answer:

x = 114

Step-by-step explanation:

Given

[tex]\frac{x+18}{4}[/tex] = 33 ( multiply both sides by 4 to clear the fraction )

x + 18 = 132 ( subtract 18 from both sides )

x = 114

Answer:

y = -2x + 7

Explanation:

y = mx + b

m = slope

b = y-intercept

y = a given y coordinate

x = a corresponding x coordinate

First, we need to find the slope (m).

1) (4, -1)

2) (2/3)

m = slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{3-(-1)}{2-4}[/tex] = [tex]\frac{4}{-2}[/tex] = -2

plug in the values to the equation y = mx + b

-1 = -2(4) + b

-1 = -8 + b

7 = b

now, we can substitute in m and b into the equation y = mx + b

y = -2x + 7

Answer:

figure 1 is 8.5 units^2 and figure 2 is 3 units^2 and the average are is 5.25 units^2

The overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Since the area is covered with either a square or a triangle. Therefore, we can write the area of this two as,

Area of a square = 1 unit × 1 unit = 1 unit²

Area of triangle = 0.5 × 1 unit × 1 unit = 0.5 units²

The overestimated area, the number of square and triangles are,

Number of square = 6

Number of triangle = 5

Total overestimated area = (6×1unit²) + (5×0.5unit²) = 8.5 unit²

The under estimated area, the number of square and triangles are,

Number of square = 2

Number of triangle = 2

Total Underestimated area = (2×1unit²) + (2×0.5unit²) = 3 unit²

Furthermore, the average area is,

Average area = (Total overestimated area - Total Underestimated area)/2

                       = (8.5 units² - 3 units²) / 2

                       = 5.5  units² / 2

                       = 2.75 units²

Hence, the overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

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

We always follow these rules when we are Multiplying and Dividing numbers with Scientific Notation.

1. If the numbers are not in scientific notation, convert them.

2. Regroup the numbers using the commutative and associative properties of exponents.

3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.

             -Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾  to multiply the bases.

4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.

5. Join the new coefficient to the new power of 10 to get the answer.

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

Let's start!

Our equation:

                                  (5.2 × 10⁶)(7 × 10⁸)

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

1. If the numbers are not in scientific notation, convert them.

They are in scientific notation, so we go on to step 2.

2. Regroup the numbers using the commutative and associative properties of exponents.

(5.2 × 7)(10⁶ × 10⁸)

3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.

             -Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾  to multiply the bases.

5.2 × 7 = 36.4

10⁶ × 10⁸= 10⁽⁶⁺⁸⁾ = 10¹⁴

4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.

36.4 = 3.64 × 10¹

5. Join the new coefficient to the new power of 10 to get the answer.

3.64 × 10¹ × 10¹⁴

3.64 × 10⁽¹⁺¹⁴⁾ = 3.64 × 10¹⁵

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

3.64 × 10¹⁵

Answer:

Step-by-step explanation:

there isnt anything to circle so but since he was 4, 8 years ago, you would add 4 and 8.

Answer:

Part a) to find the maximum height of the snowball, you have to differentiate the function. Therefore you get ----> dh/dt= -32x-8 . Now equate this to zero and solve for x. x= (-1)/4 now sub this value in to find h(x) [note: i'm talking about the original function] . I got h max = h((-1)/4) = 9 which is the max height.

Explanation:

The formula for the area of a circle is A = πr²,

where:
