Answer:
Step-by-step explanation:
1)
?/10 =4/5
?/5×2 =4/5
4×2/5×2 =8/10 ... the number is : 8
2)
?/4 = 11/4....the number is : 11
-3
Because -2^2-8+1
-2to the second power is 4
4-8=-4
-4+1=-3
Answer:
The length of the rectangle is of 9 units.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots
such that
, given by the following formulas:



Area of a rectangle:
A rectangle has width
and length
. The area is the multiplication of these measures, that is:

The length of a rectangle is the sum of the width and one.
This means that
, or 
The area direct angle 72 units. What’s the length, in units, of the rectangle
We want to find the length. So



Quadratic equation with
. So



Since the length is a positive measure, the length of the rectangle is of 9 units.
i-okay,whats yoour problem? maybe i can help :D
Answer:
=50x+116
Step-by-step explanation:
5+5x(10)−88+200−1
=5+50x+−88+200+−1
Combine Like Terms:
=5+50x+−88+200+−1
=(50x)+(5+−88+200+−1)
=50x+116
