Step-by-step explanation:
so basically they are asking you to subtract, hope this helps, use a calculator if needed
Answer: Length = 15 meters
Width = 2 meters
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
Area of a rectangle = l × w
where l = length
w = width
Therefore,
2l + 2w = 34 ...... i
l × w = 30 ........ ii
From equation i
2l + 2w = 34
Divide through by 2.
l + w = 17 ...... iii
Then, l = 17 - w ........ iv
Put equation iv into ii
l × w = 30
(17 - w) × w = 30
17w - w² = 30
w² - 17w + 30 = 0
w² - 15w - 2w + 30 = 0
w(w - 15) - 2(w - 15) = 0
(w - 2) = 0
w = 0 + 2 = 2
w - 15 = 0
w = 0 + 15 = 15
Length = 15 meters
Width = 2 meters
Answer:
See below in bold.
Step-by-step explanation:
1. 0.00000402
= 4.02 * 10^-6 (Counting the digits after the decimal point until we get to the 4 gives us the -6).
2. 1,900,000
= 1.9 * 10^6 ( counting the number of digits after the 1 gives us 6).
First of all, expand the left hand side:
Sum like terms:
Add 3 to both sides:
Subtract 3x from both sides:
So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
We have the following function:
N (k):
Where, the indepent variable is k
The dependent variable is N
For the function:
k (n):
the independent variable is n
The dependent variable is k
Thus,
N (12) = 4
k (4) = 12
Answer:
TRUE
option A
