Find the surface area of a rectangular prism that has the following dimensions.

length: 4.5 in.
width: 6 in.
height: 12 in.
surface area = a0 in.2

Surface Area is 306

Step-by-step explanation:

I go on googlw and ask what the area is and google for sum reason only gives surface area and not area so I guess thins time it worked out!

Answer is

306 ft2

A=2(wl+hl+hw)

A= 2(6*4.5 +12*4.5+12*6) = 306 ft2

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
