Answer:
Step-by-step explanation:
∠ACB and ∠ECD are vertical angles, so ∠ACB = ∠ECD.
∠D = ∠B
∠A = ∠E
△ABC and △EDC are similar because they have the same angles.
If you would like to solve 7x + 9 = 6x - 5 for x, you can do this using the following steps:
<span>7x + 9 = 6x - 5
</span>7x - 6x = -5 - 9
x = - 14
The correct result would be x = - 14.
Let us assume for starters that it is true.
The area of the square is s^2, so that is where you start.
(1 + 2*sqrt(2) ) ^2 = 1 + 4*sqrt(2) + 8 Taking 1 away form that does not leave you with 8.
Let's start again.
If all sides are reduced by 1 , but the square is retained, then the length of the side is 2sqrt(2). Now we have
s^2 = (2sqrt(2) )^2 = 4 * 2 = 8
The question is really not worded clearly enough to give an answer. I think it's true, but the language has to be twisted a bit.
Answer: I'd answer true, but don't be surprised if it is not interpreted the way I did on my second try.
The absolute value of 9 is 9. The absolute value of a number cannot be negative.
Answer:
-3.5
Step-by-step explanation:
It is halfway between -3 and -4
- R = -3 + (-4) / 2
- R = -7/2
- R = -3.5
