Find the surface area of the cuboid shown below
Answer:
Surface area of cuboid = 352 cm
Step-by-step explanation:
Given that:
Height of cuboid = 8 cm
Length of cuboid = 12 cm
Width of cuboid = 4 cm
Surface area = 2lw + 2lh + 2hw
Putting all the values;
Surface area = 2*12*4 + 2*12*8 + 2*8*4
Surface area = 96 + 192 + 64
Surface area = 352 cm
Hence,
Surface area of cuboid = 352 cm

Solve the simultaneous equations
y = 4x + 1
y = 2x^2+ 7x - 1
Answer:
[tex]Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3[/tex]
So, the required values of x are -2 and 1/2 and that of y are -7 and 3.

17. A moving truck fills up a shipment at an old
address at (-2, 1). It travels 7 blocks south and 6
blocks east to the new address. What is the
location of the new address?
Answer:
(4,-6)
Step-by-step explanation:
The y axis is the North and South direction, or up and down on the graph. Starting at point (-2,1), where y = 1, to move up add, or to move south subtract. To move 7 blocks south 1 - 7 = -6
The x axis is East and West or to the right or left respectively. To move East / right add, to move West / left subtract. In the point (-2,1) x = - 2 so to move 6 blocks east add. -2 + 6 = 4
Put the coordinates together (4,-6)
