What is the surface area of the figure shown below?
Novosadov [1.4K]
We know that 
surface area of the figure=surface area rectangular prism+surface area triangular prism

surface area rectangular prism=2*[12*6]+2*[16*6]+[16*12]---> 528 ft²

surface area triangular prism=2*[12*8/2]+2*[16*10]----> 416 ft²

surface area of the figure=528+416-----> 944 ft²

the answer is
944 ft²

Use a = -2, b = - 3, and c = 6 to write an expression that has a value of 12.
Semenov [28]

a negative times a negative = a positive

so (a * b) + c = 12

(-2 * -3) +6 = 12

6+6 = 12

Please I need help step by step
zaharov [31]
To find the surface area, you need to do the following:
A side of the figure is a trapezoid, so you should do 13+5x7 (since there are 2 of the same sides there is no need to divide by two.) and it should equal 126. To find the area of the top of the figure, you need to do 5x2 which equals 10. The area of the bottom of the figure is 26 (13x2), then do 2x3x2 to get the sides on the left and right of the figure. After all of this, add them together. (126+10+26+12=174.)
The surface area should be 174mm.

Veronika [31]

Y=0.213x-352  will represent this linear model shown in the data table.

<h3>What will be the linear model for the given data?</h3>

Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option

So if we put the value x=1980 in the Y=0.213x-352  then

Y=0.213(1980)-352

Y=69.74

These values are closest to 70.1 whereas other options do not satisfy the condition.

Thus Y=0.213x-352  will represent this linear model shown in the data table.
