Find the surface area and volume of a rectangular prism with the following dimensions: Length = 9 cm, Width = 5 cm, Height = 6 c

GrogVix [38]

Answer:

$V=L\times W \times H=9\times 5\times6=270 cm^3$

$S_A=2LW + 2LH +2WH = 2(9)(5)+2(9)(6)+2(5)(6)=258 m^2$

A gardener is installing fence around his garden. Let x represent the width of the garden, in feet. The perimeter of the garden

garri49 [273]

Perimiter=2L+2W
P=2(L+W)

if x=width then
P=2(L+x)

P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4

B is answer

Please answer Question 4.

mezya [45]

Answer:

see the explanation

Step-by-step explanation:

Part a) Graph y=2x+3

This is the equation of a straight line

To graph the line we need two points

Find the intercepts

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

$y=2(0)+3=3$

The y-intercept is the point (0,3)

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

$0=2x+3\\x=-1.5$

The x-intercept is the point (-1.5,0)

Plot the intercepts and connect them to graph the line

see the attached figure N 1

Part b) Graph 5x-2y=10

This is the equation of a straight line

To graph the line we need two points

Find the intercepts

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

$5(0)-2y=10\\y=-5$

The y-intercept is the point (0,-5)

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

5x-2(0)=10\\x=2

The x-intercept is the point (2,0)

Plot the intercepts and connect them to graph the line

see the attached figure N 2

Part c) Graph x=5

This is the equation of a vertical line (parallel to the y-axis)

All x-coordinates of the points belonging to the line will be equal to 5

see the attached figure N 3

Part d) Graph y=-4

This is a horizontal line (parallel to the x-axis)

All y-coordinates of the points belonging to the line will be equal to -4

see the attached figure N 4
