3. The length of a rectangle is 3 cm greater than its width. The perimeter is 24 cm. What are the dimensions of the rectangle?
Let the width of the rectangle be x cm.
a) Then the length of the rectangle in term of "x" is..

b) The perimeter of the rectangle is 24 cm. Write an algebraic equation (formula) in terms of x to show the perimeter of the rectangle.

c) Solve the equation for x and hence state the dimensions of the rectangle.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

if i put something wrong your not gonna like it so rather not say nothing.

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
