Answer:
x=70 angle b = 70 and angle c=72
Step-by-step explanation:
all triangles add up to 180 so the equation is 2x+40=180
Given: Different equations
To Determine: Which would be best solved using difference of two squares
Solution
The factorization of a difference of two squares is given below
Let us examine each of the given equation
From the above,
The two equation above can be solved by difference of two square, but the equation below is the easiest solved using differnce of two square
x² - 25 = 0
Answer:
The length of the Sally's garden is 28 m and width is 8 m.
Step-by-step explanation:
Here, let the width of the garden = k meters
So, the length of the garden = (3 k + 4) meters
Perimeter of the garden = 72 m
Now, the Perimeter of the Rectangle = 2 (LENGTH + WIDTH)
⇒ 2( k + (3 k + 4)) = 72
or, 2 ( 4 k + 4) = 72
⇒ 8 k + 8 = 72
or, 8 k = 72 - 8 = 64
⇒ k = 64/8 = 8
or, the Width of the garden = k = 8 meters
and the Length of the garden = (3k + 4) = ( 3 x 8 + 4) = 28 meters
So, the length of the Sally's garden is 28 m and width is 8 m.
