Answer:
3x² - 9x + 5
Step-by-step explanation:
Given
(5x² - 3x + 4) - (2x² + 6x - 1)
Distribute the first parenthesis by 1 and the second by - 1
= 5x² - 3x + 4 - 2x² - 6x + 1 ← collect like terms
= (5x² - 2x²) + (- 3x - 6x) + (4 + 1)
= 3x² - 9x + 5
Answer:
28 centimeters.
Step-by-step explanation:
Let w be width of desk.
We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.
Since the area of trapezoid is half the sum of parallel sides times its height.
, where
h= Height of trapezoid,
a and b= Length of parallel sides of trapezoid.
We have been given that the height of the trapezoid is the width of the desk.
Upon substituting our given vales in above formula we will get,
Therefore, the width of trapezoid is 28 centimeters.
Answer:
The answer to your question is 10 dm
Step-by-step explanation:
Data
length of a rectangle = x + 4
height of a rectangle = x - 6
Area of the rectangle = 56 dm²
length of the square = x
Process
1.- Find x with the information given for the rectangle
Area = length x height
Substitution
56 = (x + 4)(x - 6)
Expand
56 = x² - 2x - 24
Equal to zero
x² - 2x - 24 - 56 = 0
Simplify
x² - 2x - 80 = 0
Factor
(x - 10)(x + 8) = 0
Equal to zero
x₁ -10 = 0 x₂ + 8 = 0
x₁ = 10 x₂ = -8
2.- Conclusion
The length of the square is 10 dm because there are no negative lengths.
Answer:
1
Step-by-step explanation:
The y-coordinate is 4, so we count 4 units up the y-axis from the x-axis. You can also look at it as counting 4 units up from the origin. Then, we look at graph C. When y=4, when we're 4 units above the x-axis, x=1 since the point on the line falls 1 unit to the right of the y-axis.
I hope this helps!
