Answer from: ncontreras06

Step-by-step explanation:

x^3+7x^2+5x^2+35x

= x^3+12x^2+35x

Answer from: genyjoannerubiera

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

Answer from: Quest

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

Answer from: Quest

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

= $\sqrt{(9-6)^{2} +(12-6)^{2} } \\=\sqrt(45)=3\sqrt(5)$

side j'k'=distance between j' and k'

= $\sqrt{(3-2)^{2} +(2-4)^{2} } \\=sqrt(5)$

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
