The three rectangular faces have area:
5 x 2 = 10
5 x 3 = 15
5 x 2 = 10
Total = 35

The two rectangular faces each have area of
(1/2) x 2 x 2 = 2
Total = 4

35 + 4 = 39

The answer is 39 square inches.

The triangular prism has 5 faces; two triangle faces and three rectangular faces.

We can find the area of one of the triangle faces by doing ((base * height) / 2). In this case, it would be ((2 * 2) / 2), which of course would equal 2"². Multiplied by two for the two triangles, which would be 4.

To find the area of one of the rectangles, we do (length * base), which would be (5 * 2) in our case, giving us 10. Multiply by 3 for the 3 faces, and we got 30"².

30 + 4 = 34"²

Write an iequality for -5(×+7)<-10 representing the solution for x​
vovikov84 [41]

Answer:

X<-5

Step-by-step explanation:

1) open the brackets

2) take -35 to the other side with -10

where it turns to be -5X<-10+35

3) work out to find -5X<25

4) divide both sides by -5

to find X<-5

Help me pls guys/girls
Kamila [148]

Answer:

 V = 9.828 * 10^7 mm^3

a= 9.828  b = 7

9,827,000  mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3  * 3.9*10^2  * 2.1*10^2

We multiply the numbers out front and add the exponents  (the powers of 10)

V = (1.2*3.9*2.1)  * 10^(3+2+2)

 V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left.  Since there is not enough places add zeros

9,827,000  mm^3

Answer:

See image

Step-by-step explanation:

To graph the inequality

-2x + y >= -10

Change it to y = mx + b form, use a solid line (bc of the "or equal to" underline)

y >= 2x - 10 We have y-intercept at -10 and slope 2/1, shading goes above the line.

The other graph is an absolute value graph; it has a v-shape. The 7 makes it stretched 7 times taller (and skinnier) the -4 by the x shifts the whole graph to the right 4 units. The -4 at the end of the equation shifts the whole graph down 4 units. See image. The shading goes above the V (kind of looks like inside)

The solution to the system is where the shading of the two overlap. It is mostly the shading for the absolute value graph except for a tiny triangle at the bottom. See image.
