Answer:

$\Huge\boxed{2x^3+5x^2-7x+20}$

Step-by-step explanation:

$\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd$

$(x+4)(2x^2-3x+5)\\\\=(x)(2x^2)+(x)(-3x)+(x)(5)+(4)(2x^2)+(4)(-3x)+(4)(5)\\\\=2x^3-3x^2+5x+8x^2-12x+20\\\\\text{combine like terms}\\\\=2x^3+(-3x^2+8x^2)+(5x-12x)+20\\\\=2x^3+5x^2-7x+20$

If Hana is puting the fruit she bought into bowls.she bought 8 melons,12 pears,and 24 apples. She puts the same number of peices

kherson [118]

Answer: There are 2 melons, 3 pears and 6 apples in each bowl.

Step-by-step explanation:

Since we have given that

Number of melons = 8

Number of pears = 12

Number of apples = 24

We need to find the number of pieces that Hana can put in each bowl.

For greatest number of pieces = H.C.F. of 8, 12, 24 =4

So, Number of pieces of melons = $\dfrac{8}{4}=2$

So, Number of pieces of pears = $\dfrac{12}{4}=3$

So, Number of pieces of apples = $\dfrac{24}{4}=6$

Hence, there are 2 melons, 3 pears and 6 apples in each bowl.
