Answer:
The perimeter of rectangle is
Step-by-step explanation:
Let
x------> the length of rectangle
y----> the width of rectangle
we know that
The area of the constructed figure is equal to
so
-----> equation A
-----> equation B
substitute equation B in equation A
using a graphing calculator to resolve the quadratic equation
the solution is
Find the value of x
Find the perimeter of rectangle
The perimeter of rectangle is equal to
Question:
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
Step-by-step explanation:
Given
<em></em><em> --- It is negative because he is climbing down</em>
Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.
This can be rewritten as:
The product, when written as sum is:
Don’t quote me but I think it’s Choice 3.
Answer:
r=1
Step-by-step explanation:
77 - 88 = -11
