Simplify the expression to a polynomial in standard form: (4x+5) (x^2-3x-2) PLEASE HLEP
pickupchik [31]

Answer:

4x^3-7x^2-23x-10

Step-by-step explanation:

So we have the expression:

(4x+5)(x^2-3x-2)

Distribute. Multiply (4x+5) to each term:

(x^2)(4x+5)+(-3x)(4x+5)+(-2)(4x+5)

Distribute:

=(4x^3+5x^2)+(-12x^2-15x)+(-8x-10)

Combine like terms:

=(4x^3)+(5x^2-12x^2)+(-15x-8x)+(-10)

Add and simplify:

=4x^3-7x^2-23x-10

And this is in descending order, so it's in standard form.

Luba_88 [7]

Answer:

Juan would need to fill up the 1/4 measuring cup 24 times.

Step-by-step explanation:

So to measure one cup of flour with a 1/4 measuring cup, you would need to fill up the 1/4 measuring cup 4 times. Since we want 6 cups, you would need to fill up the 1/4 measuring cup 24 times. 6 times 4 = 24. Hope this helps!
