Given the quadratic equation:
Using the general solution for quadratic equations:
From the problem, we identify:
Then:
And the solution set is:
The surface area of the box will be 112 in²
Explanation
According to the given diagram, the shape of the box is Right Rectangular prism.
The formula for the surface area is :
, where length, width and height of the rectangular prism
Given in the diagram that,
So, plugging the values into the formula...
So, the surface area of the box is 112 in²
Corresponding angles postulate, as the two 35 degree angles are corresponding.
Answer:
(r+s) (x) = 4x+3
(r*s) (x) = 3x^2 +x-4
(r-s) (-1) = -3
Step-by-step explanation:
r(x) = x-1
s(x) = 3x+4
(r+s) (x) = x-1 + 3x+4
Combine like terms
= 4x+3
(r*s) (x) = ( x-1) ( 3x+4)
FOIL
= 3x^2 +4x-3x-4
= 3x^2 +x-4
(r-s) (x) = x-1 - (3x+4)
Distribute the minus sign
=x-1-3x-4
=-2x-5
Let x = -1
(r-s) (-1) = -2(-1) -5
2-5
-3
Answer:
The two numbers are 8 and 4
Step-by-step explanation:
x is one number
y is the other number
x+y = 12
x - y = 4
Add the two equations together
x+y = 12
x - y = 4
-----------------
2x = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 12
8+y = 12
y = 12-8
y = 4
The two numbers are 8 and 4
