Monica found the volume of the prism below using the expression 4 + (4 times one-half).What errors did Monica make? Check all that apply. She should have counted only 2 unit cubes instead of 4. She should have counted 8 one-third cubes instead of only 4. She should have found the total value of the one-third cubes by multiplying by One-third instead of by One-half. Each fractional cube is worth Two-thirds instead of the One-half that she used. She cannot stack more than one layer of fractional cubes in a prism.

b, i believe, but not sure.

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

answer: im sorry i dont get it
