Show that 4(m + 7) + (m + 3)^2 = (m + 3)(m + 7) + 16

anygoal [31]

Step-by-step explanation:

$4(m+7)+(m+3)^2=(m+3)(m+7)+16\\\\L_S=4(m+7)+(m+3)^2\\\\\text{use the distributive property}:a(b+c)=ab+ac\\\text{and formula}:\ (a+b)^2=a^2+2ab+b^2\\\\L_S=(4)(m)+(4)(7)+m^2+2(m)(3)+3^2\\\\L_S=4m+28+m^2+6m+9\qquad\text{combine like terms}\\\\L_S=m^2+(4m+6m)+(28+9)\\\\L_S=m^2+10m+37$

$R_S=(m+3)(m+7)+16\\\\\text{use FOIL}:(a+b)(c+d)=ac+ad+bc+bd\\\\R_S=(m)(m)+(m)(7)+(3)(m)+(3)(7)+16\\\\R_S=m^2+7m+3m+21+16\qquad\text{combine like terms}\\\\R_S=m^2+(7m+3m)+(21+16)\\\\R_S=m^2+10m+37\\\\\boxed{L_S=R_S}$

What is the distance between the points (-4,-8) and (10,-8)?

ioda

Answer: 14

Step-by-step explanation:

Input Data :

Point 1 ( x A , y A ) = (-4, -8)

Point 2 ( x B , y B ) = (10, -8)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √ (x B − x A ) 2 + ( y B − y A ) 2

Solution :

Distance between two points = √ ( 10 − − 4 ) 2 + ( − 8 − − 8 ) 2

= √ 14 ^2 + 0 ^2

= √ 196 + 0

= √ 196 = 14

Distance between points (-4, -8) and (10, -8) is 14
