10+12x would be the answer
Answer: The answer is (b) △ABC is similar to △JKL by AA Similarity Postulate .
Step-by-step explanation: We are given a triangle ABC with ∠B = 65° and ∠C = 65°. We are to find the triangle among the other three options which ΔABC similar to.
We can see that in △JKL, we have
∠K = 65° and ∠L = 65°.
Therefore, in ΔABC and ΔJKL, we have
∠B = ∠K,
∠C = ∠L.
So, by AA similarity postulate, we get
ΔABC ≈ ΔJKL.
Thus, the correct option is (b) △ABC is similar to △JKL by AA Similarity Postulate .
28/6 is 4 2/3 in simplest form
The way we arrive at this answer is
6 can be divided from 28 at least 4 times maximum.
6 times 4 is 24.
28 - 24 = 4.
The 6's that have been taken away from the fraction becomes 1's, because 6/6 is equivalent to 1.
Therefore, 1 times 4 is 4, because we had taken away from the fraction 4 times.
What you get is 4 4/6. However, that is not in simplest form yet.
4/6 can be simplified to 2/3 by dividing by two.
The answer you should get is 4 2/3
Circumference: 2πr
Circumference: 2(3.14)(x + 1)
Circumference: 6.28(x + 1)
Circumference: 6.28(x) + 6.28(1)
Circumference: 6.28x + 6.28
Area: πr²
Area: 3.14(x + 1)²
Area: 3.14(x +1)(x + 1)
Area: 3.14(x(x + 1) + 1(x + 1))
Area: 3.14(x(x) + x(1) + 1(x) 1(1))
Area: 3.14(x² + x + x + 1)
Area: 3.14(x² + 2x + 1)
Area: 3.14(x²) + 3.14(2x) + 3.14(1)
Area: 3.14x² + 6.28x + 3.14
Answer:
24
Step-by-step explanation:
You need to plug in 3 for all of the x-values
That looks like 2(3)^2 + 5(3) - 9
Then if you simplify it is 2(9) + 15 - 9
Then simplify one last time and you get a final answer of 24
