Nikita's work
area of base = b = 3 bn=(718) = 28 cm?
volume=bh= (28)(13) = 364 cm
where, if any, did nikita first make a mistake in her work?
nikita used the wrong formula for the area of the base.
nikita used the wrong measurements when finding the area of the base.
nikita used the wrong formula for the volume of the prism.
nikita did not make a mistake.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

step-by-step explanation:

sry but any answer choices

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

b is the correct answer
