The area of the cross-section is 169 sq. cm.
That is the correct answer to this problem
Answer:
Least to greatest: 2, 3, 1
Step-by-step explanation:
Square root of 8 over 2 is about 1.41 which makes it the least value
2 is obviously equal to 2 which puts it in the middle
Square root of 7 is about 2.64 which makes it the greatest value
Answer:
(5a - [2b - 7c]) and (5a + [2b + 7c])
Step-by-step explanation:
Factor 25a^2 - 4b^2 + 28bc - 49c^2.
Note that - 4b^2 + 28bc - 49c^2 involves the variables b and c, whereas 25a^2 has only one variable. Thus, try to rewrite - 4b^2 + 28bc - 49c^2 as the square of a binomial:
- 4b^2 + 28bc - 49c^2 = -(4b^2 - 28bc + 49c^2), or
-(2b - 7c)^2.
Thus, the original 25a^2 - 4b^2 + 28bc - 49c^2 looks like:
[5a]^2 - [2b - 7c]^2
Recall that a^2 - b^2 is a special product, the product of (a + b) and (a - b). Applying this pattern to the problem at hand, we conclude:
Thus, [5a]^2 - [2b - 7c]^2 has the factors (5a - [2b - 7c]) and (5a + [2b + 7c])
Answer:
7/6 or 1 1/6
Step-by-step explanation:
First convert 2 1/3 into just a normal fraction
2 1/3 = 7/3
Next set up the equation and multiply from left to right on both the top and bottom.
1/2 x 7/3 = 7/6
1 x 7 = 7
2 x 3 = 6
Answer: 7/6 or 1 1/6
Answer:
Answer: B, 6/11
Step-by-step explanation:
<em>Well we know that 3+2+1=6+3=9.</em>
<em>So that means we will add the 2 brown crayons to the denominator.</em>
<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>
<em>6/11 is also the smallest number that you can get.</em>
<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>
<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>
Hope this helps, and if it did I would appreciate it if you marked me as Brainllest. Have a wonderful day!
