Since it is given that one hole = 0,79m^2
0,79=3,142 x radius^2
radius^2=3,142 Divided by 0,79
radius=Square Root of 3.97721512
radius=1.994295662
=1.99m^2 (3 Significant Figures)
Answer:
D) 16x^2 + 4x
Step-by-step explanation:
So a since there is two lengths and two height, you are gonna have to add them all up.
<u>5x^2 + 2x</u> + <u>5x^2 + 2x</u> + <u>3x^2</u> + <u>3x^2</u>
<u>(</u>See why I put the length value and width value twice? Because there is two of each.)
Now start adding up common factors. Let's start with any x^2
10x^2+2x + 2x + 6x^2
I added up the 5x^2 together to get 10x^2 and I added the 3x^2 together to get 6x^2, now you are gonna add those two up
16x^2 + 2x + 2x
(Just from looking at this, you can easily cross out answers A and B)
Now add the x together
16x + 4x
So the the answer is D
The answer to this question is D because the numbers is essentially 1.8...
Answer:
x = -3/13
Step-by-step explanation:
Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.
--> Thus the equation becomes:
3 ⋅ (10x+4) = (2x+3) ⋅ 2
--> Simplify
30x + 12 = 4x + 6
--> Combine Like Terms
26x + 12 = 6
26x = -6
--> Divide each term and simplify
x = -3/13
Hope this helps!
Answer:
14
Step-by-step explanation:
divide 48 by 3 = 16
they must be consecutive even numbers
2 less than and two more than 16 are 14 and 18
14 + 16 + 18 = 48
the smallest is 14
