If x is an even integer represent the next 3 even integer.

1 answer:

5 0

If x is even, say it's 2. Then what do you need to get to the next even integer (4)? You need to +2. So it would be x + 2, x + 4 and x + 6.
Or, it could be x multiplied. I.e. 2x = 4, 3x = 6, and so on so forth.

Simplify 2x(5x + 3) + 7(5x + 3)

zubka84 [21]

Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute

2x•5x = 10x^2
2x•3= 6x

10x^2+6x

7•5x = 35x
7•3= 21

35x+21

2. combine like terms

10x^2+6x+35x+21

10x^+ 41x +21 [final answer]

a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio

svlad2 [7]

We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is $\frac{1}{3} r^{2} \pi h$

We need to find the radius of the base of the cone
$535= \frac{\pi r^{2}8} {3}$
$535*8= \pi r^{2}$
$\frac{4280}{\pi}= r^{2}$
$r= \sqrt{ \frac{4280}{ \pi} }$
$r=36.9$ to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm

Find the slope of the line that passes through the two points (0,1) and (-8, -7)

Crazy boy [7]

Answer:

<h3>The slope of the line is 1</h3>

Step-by-step explanation:

The slope of a line is found by using the formula

$m = \frac{y2 - y1}{x2 - x1}$

where

m is the slope and

(x1 , y1) and ( x2 , y2) are the points

Substituting the above values into the above formula we have

Slope of the line that passes through

(0,1) and (-8, -7) is

$m = \frac{ - 7 - 1}{ - 8 - 0} = \frac{ - 8}{ - 8} = 1$

<h3>The slope of the line is 1</h3>

Hope this helps you

the wilsons back yard is rectangular plot that has a length of 100 feet and a width of 80 feet .the family planted a garden with

Irina-Kira [14]

the area in square feet is 4400. (because to find the area of the rectangle you multiply the 2 side lengths, 100 and 80 which gives you 8000, then you find the area of the square, multiply 60 by 60 which is 3600, then you subtract the total area of the backyard by the area taken up by the garden, 8000-3600, which gives you your total of 4400.)
