ANSWER
The length of a Diameter is 3.714
EXPLANATION
The circumscribed triangle is shown in the attachment.
We use the cosine ratio to find the altitude of the isosceles triangle.
Altitude =8cos(60°)
Altitude=4cm
Let the upper half of the altitude be y cm.
Then the radius of the circle is (y-4)cm
The upper radius meets the tangent at right angles.
From the smaller right triangle,
y=1.857
The diameter is 2y
=2(1.875)
The length of a Diameter is 3.714
Answer:
The first one
Step-by-step explanation:
Answer:
1. A. 4 terms
There are 4 different values in the expression, so therefore there are 4 terms.
2. D. 3x^2 + 6x + 10
To get the answer...
start with the original expression: 3x^2 + x + 10 + 5x
add the like terms together, in this case you'd add x + 5x
you'll get: 3x^2 + 6x + 10

Answer:
6a + 1
Step-by-step explanation:
First, you need to multiply everything in the brackets by 3L
(7 + 2a) x 3 =
7 * 3 = 21
2a * 3 = 6a
21 + 6a
Now you can subtract the 20 from this:
6a + 21 - 20
Simplified down:
6a + 1
