Answer:
2 Hours
Step-by-step explanation:
First you have to add up all the points which would be;
1 1/2 + 1 1/2+ 2 1/2+ 2 1/2= 8 hours
Then you have to divide by how many points to find the average;
8 hours divided by 4 points= 2 hours average

Area of a triangle is 1/2 x base x height.
The graphed triangle has height of 2 and base of 2.
Area = /2 x 2 x 2 = 2 square units.
The triangle gets enlarged by a scale factor of 2, so the new height would be 2 x 2 = 4 and the new base would be 2 x 2 = 4
Area of enlarged triangle = 1/2 x 4 x 4 = 8 square units.
The answer is C) 8
Answer:
I am not entirely sure what you are asking here but if I am right then the answer is -4(x-2) = 8 - 4x
Step-by-step explanation:
Multiplying binomials all you have to do is distribute the 4
Multiply -4 by x to get: -4x
Muliply -4 by -2 to get: 8 (Because two negatives make a positive)
Now you have -4x + 8
Rewrite so it flows better and the answer is:
8 - 4x
It can be b), c) and d).
b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.
c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.
d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.
a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)
