if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get
Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get
add both equations and you get
The answer is 14cm! Don't forget to label. ;)
Answer:
x< -
Step-by-step explanation:
x 8x_16>8x+64
Add similar elemants:x - 8x= -7x
-7x - 16 > 8x + 64
Add 16 to both sides
-7x- 16 + 16 > 8x + 64 + 16
Simplify
- 7x > 8x + 80
Subtract 8x from both sides
-7x - 8x > 8x + 80 - 8x
Simplify
-15x > 80
Multiply both sides by - 1 ( reverse the inequality)
(-15x) ( - 1) < 80 ( - 1 )
simplify
His new time compared with the old time was increased by factor of 2
<h3>Further explanation</h3>Acceleration is rate of change of velocity.
<em>a = acceleration (m / s²)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!
This problem is about Kinematics.
In this problem we assume that the unicorn is moving at a constant speed so that the acceleration is zero.
<u>Given:</u>
first distance = d₁ = 50 miles
second distance = d₂ = 300 miles
v₂ = 3 v₁
<u>Unknown:</u>
t₂ : t₁ = ?
<u>Solution:</u>
To find his new time , we will use the following formula.
