Answer:
Step-by-step explanation:
The tick marks you see on the sides denote congruence. If they have the same number of tick marks, then their side length are congruent.
And, recall that congruent side lengths have the same measure.
So, look at the sides with 2 tick marks. They are congruent. Therefore:
Subtract x from both sides:
Subtract 5 from both sides:
So, x is 7.
Now, look at the sides with only 1 tick mark. Again, they are congruent. Thus:
We already know x is 7. So:
Add:
Add 4 to both sides:
So, y is 16.
Answer:
choice A. 9 is the degree.
Step-by-step explanation:
5х^5 + 8х^2 + 2х - 3x^9 - 8x^4 - 4х^5
to find the degree of this polynomial, you must look for the highest number in the exponent.
Here it appears to be 9 in the -3x^9 term
Answer:9x10⁴
Step-by-step explanation:
1.7x10⁵-8*10⁴=10⁴(1.7x10-8)=10⁴(17-8)=9x10⁴
Answer: B 3/10
When you add all the coins together, you get a sum of 90. To find the probability of the copper coin, you get 27/90. once simplified you get the answer 3/10.
hope this helps :)
Step 1 gives you
3*(4x - 2) on the left hand side.
When you remove the brackets what you get is
3*4x - 3*2
12 x - 6 You have to distribute on both sides of the plus sign. The answer is the second one down.
So the answer is 2) <<<< answer.
