Answer:
the center (h,k) is the point (-4,5) and the radius is 11
Step-by-step explanation:
<span>A+B)^2 is the largest. It is A^2+2AB+B^2, which is clearly greater than the last two options. To compare (A+B)^2 and 2(A+B), we remove one A+B so that we're just comparing A+B and 2. As A+B must be at least 3 (as both must be positive integers, and one must be greater than the other, leading to a minimum value of A=2, B=1), A+B is greater than 2, and as a result, (A+B)^2 is always the largest.</span>
Answer:
V = 112
Step-by-step explanation:
Volume = Area of the base x height, so area of the triangle is 1/2(8)(4) = 16
Volume = 16 x 7 = 112
Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x
BD ≈ 5.36
Answer:
1. x = 10
(triangle has equal side lengths)
2. x = the same number inside the triangle
(is that a 40 or 80?)
3. x = 34
(is that a 34?)
4. x = the number shown on the other side of the triangle
(is that a 55?)
5. if the given number is 8 then x = 11
(11-3=8)
6. x = 11
(2x-15=7)
7. x = 5
(65+5=70)
8. x = 10
(5x-10=40)
9. m<2 = 9
(7x-3=60)
10. m<2 = 8
(x+72=80)
hope this helps!
