We need to distribute the term 4x to x - 6. Basically, we need to multiply 4x by x, which gives us 4x², and 4x by -6, which gives us -24x. Putting our two derived terms together, we get 4x²- 24, which is your answer. Hope this helps and have a great day!
Width of the rectangle is 13 cm and length is 29 cm.
<u>Step-by-step explanation:</u>
Step 1:
Given perimeter of the rectangle = 84 cm. Let the width be x, then the length of the rectangle = 2x + 3. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.
84 = 2(2x + 3 + x) = 2(3x + 3) = 6(x + 1) [taking 3 as common factor outside)
⇒ 84 = 6x + 6
⇒ 78 = 6x
∴ x = 13
⇒ Width of the rectangle = 13 cm
∴ Length of the rectangle = 2x + 3 = 29 cm

Answer:
<em>Gradient of KL = 2</em>
Step-by-step explanation:
From the diagram, we are to calculate the gradient of KL. Gradient is salso known as the slope of the line.
Gradient of KL = ΔOK/ΔOL
Given
OK = 2OL
Substitute into the formula
From the diagram, ΔOL = -5
ΔOK = 2ΔOL
ΔOK = 2(-5)
ΔOK = -10
Hence;
Gradient = -10/-5
<em>Gradient of KL = 2</em>

Answer:
(0, 5)
Step-by-step explanation:
You get y-intercept when x=0
<u>For the given equation y-intercept is:</u>
As a point on the graph it is: (0, 5)
Here y-intercept may represent flat rate of monthly fee.
