Answer:
dang that is hard
Step-by-step explanation:
1/1+z+4/z+z^2 +1
1/2z =4/2z^2 +1
1/2z=2(z^2+2)/2z^2
1/2z=z^4+2z^2
z^5/2+2z^2
=therefore it has no solution I think this is the stes i m not sure sorry i m not sure ,try asking somebody else to cuz i m not sure
Length of wall is 16 feet and breadth is 4 feet.
Step-by-step explanation:
- Step 1: Given area = 64 sq. ft, length is breadth + 12 ft. Let breadth be b.
So length, l = b + 12
- Step 2: Substitute in area for rectangle = length * breadth
⇒ (b + 12) * b = 64
⇒ b² + 12b = 64
⇒ b² + 12b - 64 = 0
- Step 3: Solve for b using equation for finding roots of quadratic equation
Roots = (- b ±√b² - 4ac)/2a
⇒ b = (- 12 ±√144 - 4 * 1 * - 64)/2
= (-12 ±√144+256)/2 = (-12±√400)/2
= (-12±20)/2
= 4, -16 (negative is neglected)
⇒ breadth is 4 feet
- Step 4: Length = b + 12 = 16 feet
Answer:
The parallel line would be y = 2
Step-by-step explanation:
In order to find a parallel line, we first must know that the original line (y = 5) is a horizontal line. This means all lines parallel to it will also be horizontal.
Horizontal lines all can be written in the form of y = (a number). Since we have an ordered pair, we can choose the y value to fill that number.
y = 2
Answer:
She could plant 9 plants.
Step-by-step explanation:
1 1/2 hours = 90 minutes, so 12 plants per 90 minutes. Which would mean 6 plants per 45 minutes. So in between 45 and 90 minutes (1 hour), and in between 6 and 12 plants (9).
Sorry if you didn't understand, I'm bad at explaining.
