Answer: it has a 20% increase
Answer: The width is 14m
Step-by-step explanation: The question has provided the perimeter as 60. The available clues are such that the length measures 2m more than it's width. This means whatever is the width of the rectangle, the length shall be equal to plus 2. Hence, if the width is W, the length is W + 2.
So we have,
Perimeter = 60
Length = W + 2 and
Width = W
Already the perimeter is given as
Perimeter = 2(L + W)
We can now express the perimeter as follows;
60 = 2(W + 2 + W)
60 = 2(2 + 2W)
By cross multiplication we now have
60/2 = 2 + 2W
30 = 2 + 2W
Subtract 2 from both sides of the equation
28 = 2W
Divide both sides of the equation by 2
14 = W.
Remember that the length is given as W + 2, so the length becomes
14 + 2 = 16
Therefore, the width equals 14 m.
6a
So you would write the factored equation as 6a(b+2)
Answer:
z = 1, z = 9
Step-by-step explanation:
Given
z² + 9 = 10z ( subtract 10z from both sides )
z² - 10z + 9 = 0
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)
The factors are - 1 and - 9, since
- 1 × - 9 = 9 and - 1 - 9 = - 10, thus
(z - 1)(z - 9) = 0 ← in factored form
Equate each factor to zero and solve for z
z - 1 = 0 ⇒ z = 1
z - 9 = 0 ⇒ z = 9
Answer:
y = -x + 9
Step-by-step explanation:
Since the line is parallel, the slope is -1.
y = -x + c
Substituting (0,9) into the above equation:
9 = 0 + c
c = 9
y = -x + 9
