If the width is w then the length = 2w + 40, so the area

= w(2w + 40)

= 2w^2 + 40 w

Being 10 miles apart, two cars started moving towards each other. After one hour they met, and during that time the first car co

Vladimir [108]

The speed of the first car was 6 miles/hour

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem!

<u>Given:</u>

Distance between two cars = d = 10 miles

Time Taken = t = 1 hour

Distance covered by the first car = d₁ = 2 + d₂

<u>Unknown:</u>

Speed of the first car = v₁ = ?

<u>Solution:</u>

$d = d_1 + d_2$

$10 = ( 2 + d_2 ) + d_2$

$10 = 2 + 2d_2$

$10 - 2 = 2 d_2$

$8 = 2 d_2$

$d_2 = 8 \div 2$

$d_2 = 4 \texttt{ miles}$

$\texttt{ }$

$d_1 = 2 + d_2 = 2 + 4 = 6 \texttt{ miles}$

$v_1 = d_1 \div t = 6 \div 1 = 6 \texttt{ miles/hour}$

Heres what i needed help with

PART A
move 2/3 to the right side so we could find the value of A
(2/3)A = -24
A = -24 ÷ 2/3
A = -24 × 3/2
A = -72/2
A = -36
Point A is -36

PART B
move -0.2 to the other side so we could find the value of B
-(B)/0.2 = 20
-B = 20 × 0.2
-B = 4
B = -4
Point B is -4

PART C
Find the distance between -36 and -4
d = |-36 - (-4)|
d = |-36 + 4|
d = |-32|
d = 32
The distance of the two points is 32
