Answer:
The width of the field is 4x + 20 / x² -2x -3 yards
Step-by-step explanation:
The area of a rectangular field is given by the following formula:
area = length*width
In this case we want to find the width of this field, therefore if we isolate the width in the expression above we will have a suitable expression:
width*length = area
width = area / length
So applying the data from the problem, we have:
width = [(2x + 6)/(x + 1)] / [(x² - 9)/(2x + 10)]
width = [(2x + 6)/(x + 1)]*[(2x + 10)/(x² - 9)]
width = 2(x + 3)*(2x + 10) / (x+1)*(x - 3)*(x + 3)
width = 2*(2x + 10) / (x + 1)*(x - 3)
width = 4x + 20 / x² -2x -3
X^2 + 2x - 3 = (x-1)(x+3)
Answer:
-6
Step-by-step explanation:
Use order of operations. This gives you -11+8+(-3). Then you have -3+(-3). Then you have -3-3. Finally, -6.
Please give brainliest if this was the correct answer.
Raisin = r
blueberry = b
banana = n
r = 18
b = 3r = 18 x 3 = 54
n = b/2 = 54 / 2 = 27
total = 18+54+27 = 99
First we expand and combine the terms on the left side. This gives us
12x + 32 -4x + 8 = -8x + 40
8x + 40 = -8x + 40. Because the two sides cancel each other out when you try and bring all the x to one side, the answer is x = 0.
