The answer to this is 68.7
The tenths place is the first term right after the decimal point. We see a "6" there. Look the number right after that. There is a "9". Since 9 is greater than 5, we round up the "6" to "7".
It's unlikely that it the dimensions are either 14 and 1 in front of the x or 6 and 1 for the 6, but this is math, so you never know. I would try 7 and 2 and 3 and 2 and see what comes of it.
(7x 2)(2x 3 ) That looks promising. We'll put the 3 with the 2x. That leaves us with the signs. We need 17 to be minus
(7x 2)(2x - 3) that gives you - 21 x So the 2 with the seven has to be plus.
(7x + 2)(2x - 3) should be the the factored answer.
7x + 2 = 0 has no meaning. Measurements cannot be minus.
2x - 3 = 0
2x = 3
x = 3/2
If there are choices, please list them. That's as far as is possible.
Answer: x = 6
Step-by-step explanation:
Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.
Next, we set up the proportion as follows:
Then, you cross multiply to get the equation:
After solving down algebraically, you get the value of x to be 6.
I hope this helps!
Answer:
50.2 m^2
Step-by-step explanation:
The Area of a circle is given by the equation pi(r)^2
Therefore if r = 4 we can plug it into the equation to get:
- pi (4)^2
- = pi(16)
- = 50.2655 or about 50.2 m^2
