Answer: Third multiple choice
Step-by-step explanation:
First answer:
Since the fraction is increased by 7, we need to check if the increasing factor is the same for the bottom part of the fraction:
The first answer doesn't match, we do the same for all three remaining answer.
2)
3)
4)
In this case, the answer is the third multiple choice.
Answer:
1.3
Step-by-step explanation:
Slope = 1.3
Step-by-step explanation:
180 = 55 + 41 + y (Angles in a triangle)
y = 180-(55+41)
y = 84
y+ z = 180 (Angles on a line)
z = 180 - y
z = 180 - 84
z = 96
The lines are parallel.
The angle opposite x is 109 because the are corresponding.
x is 109 (vertically opposite angles)
Answer:
So, Width = 7/2 or 3.5
Length = 4
Step-by-step explanation:
Area of rectangle = 14 ft^2
Let width of rectangle 2 = x
and Length of rectangle = 2x-3
Formula used for area of rectangle
Area = Length * Width
14 = (2x - 3) x
14 = 2x^2 - 3x
=> 2x^2 -3x -14 = 0
Solving the quadratic equation using factorization
-28 x^2 = -7x * -4x
2x^2 -7x + 4x -14 = 0
x (2x -7) +2(2x-7) = 0
(x+2) (2x-7) =0
=> x + 2 =0 and 2x -7 = 0
x = -2 and x = 7/2
Since width cannot be negative so, x= 7/2
Width= x = 7/2
Length = 2x -3 => 2(7/2) - 3
=> 7 -3
=> 4
So, Width = 7/2 or 3.5
Length = 4.
