Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?
The probability illustrated shows that the
percent of cookies would have between 13.8 and 24.2 chips is 95.44%.
<h3>How to calculate the probability?</h3>
It is important to note that the requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.
This will be illustrated thus:
Z value for 13.8, z =(13.8-19)/2.6 =-2
Z value for 24.2, z =(24.2-19)/2.6 = 2
P( 13.8<x<24.2) =P(-2<z<2)
=P( z <2 –P(z < -2)
=0.9772 -0.0228
=0.9544
= 95.44%
The percent is 95.44%.

The cube root of a number is the number which when multiplied by itself three times give you the original number. ... The square root of a number is the number which when multiplied by itself twice give you the original number. As an example, the square root of 9 is 3 because 3×3 = 9
Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
<em>33-10=23</em> so x is 23.
hope this helped, have a great day.
