Answer:
It's the first one
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
y/x = 30/(x + 10)
(y + 12)/x = 54/(x + 10)
y/x + 12/x = 54/(x + 10)
30/(x + 10) + 12/x = 54/(x + 10)
30x + 12(x + 10) = 54x
30x + 12x + 120 = 54x
120 = 12x
x = 10
EG = x + x + 10
EG = 10 + 10 + 10
EG = 30
Answer: Equilateral
Step-by-step explanation:
Answer:
<em>The leading coefficient is 3</em>
Step-by-step explanation:
<u>Polynomials</u>
Given the roots of a polynomial x1,x2,x3, it can be expressed as:

Where a is the leading coefficient.
We are given the roots x1=-6, x2=7i, x3=-7i, thus:

Operating the product of the conjugated imaginary roots:

Knowing p(2)=1,272 we can find the value of a

Operating:


Solving:

a=3
The leading coefficient is 3
Answer:
A: 3/5 + 2/5 = 5/5
A: 3/5 + 1/5 = 4/5
B: 3/5 - 2/5 = 1/5
B: 3/5 - 1/5 = 2/5
C: 3/5 x 2/5 = 6/25
C: 3/5 x 1/5 = 3/25
C: 2/5 x 1/5 = 2/25
D: 1/2 + 1/4 = 3/4
D: 4/5 + 4/10 = 6/5
E: 4/6 ÷ 2/6 = 2
E: 1/6 ÷ 1/6 = 1
