This area model can be used to determine the product of 862 × 7. Which equation describes the multiplication calculation?

800 × 7 + 60 × 7 + 2 × 7

Step-by-step explanation:

The area of the figure equals :

Area of rectangle = Length * width

Width = 7

Length = 862

862 in expanded form:

800 + 60 + 2

Hence, Multiplying the expanded form by the width ;

(800 + 60 + 2) * 7

800*7 + 60*7 + 2*7

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
