Leena consumes 400 calories at breakfast and 350 calories at lunch. she consumes of her daily calories at dinner. if x represents the calories consumed at dinner, which statements describe the situation? check all that apply.

a. leena consumed 1,500 calories at dinner.
b. the equation 2/3(x + 400 + 350) = x can be used to model the situation.
c. leena consumed 500 calories at dinner.
d. the equation 2/3(x) = x(400 + 300) can be used to model the situation.
e. leena consumed 1,000 calories at dinner.
f. the equation 2/3x(400 + 300) = x can be used to model the situation.

Only Option 'A' and 'B' are correct.

Step-by-step explanation:

Since we have given that

Number of calories she consumed at breakfast = 400

Number of calories she consumed at lunch = 350

Let number of calories she consumed at dinner be x

According to question,

She consumes of her daily calories at dinner,

So, it becomes,

so, Number of calories she consumed at dinner is given by

And by option 'B' we get,

so, only Option 'A' and 'B' are correct.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
