Answer:
19.741
Step-by-step explanation:
When subtracting decimals line up the decimals and then add 0s to the end to make it work. SO instead of
21.25
-1.509
___________
It would be
21.250
- 1.509
______________
Solve the subtraction problem like you normally would. THen drop the decimal down so it lies up with the others.
21.250
- 1.509
______________
19.741
So, basically ..you just multiply
9*9*9*9
6561
1) substitute 10x in for the equation.
Answer:
Fewer than means that something is less than another thing. For example, the number 2 is fewer than the number 4. There's also this cool symbol that you can use instead of writing the words 'fewer than'. You could say for example 2<4. A fun way to remember which way the symbol points is to imagine it like an alligator, the number 2 is trying to eat the number 4 to grow!
Step-by-step explanation:
Hope this helps!
Area of a rectangle = length x height
Area = 135
Height = X
Lenght = x +6
135 = x * x+6
Simplify:
135 = x^2 +6x
Subtract 135 from both sides:
x^2 + 6x - 135 = 0
Solve:
2 numbers when added need to equal 6 and when multiplied equal -135
x = 9 and x = -15
The height can't be a negative number so the height is 9
Length = 9 +6 = 15
Height = 9cm, Length = 15 cm
