I can't do the fraction bar but it's 3 and 3/7
Hello!
First you have to find the ratio
To find this you put the sides of the triangles in a ratio and simplify it
Make sure you do the same side on each triangle
12 : 8
6:4
3:2
The ratio is 3:2
We do not know all three sides so we can use the SSS postulate
This tells use the answer is the SAS postulate with a ratio of 3:2
The answer is D) SAS; 3:2
Hope this helps!
• Move x to the other side
7y=21-3x
• Divide by 7
y = (21-3x)/7
Answer:
1) G
2) B
3) I
4) H
Step-by-step explanation:
Perimeter of a triangle formula:
P = a + b + c
1)
P = x + 6 + 3x + 2 + 2x + 4
P = 6x + 12
2)
P = 6x + 4 + 7x + 1 + 5x + 7
P = 18x + 12
3)
P = 4x - 3 + 3x + 5x - 6
P = 12x - 9
4)
P = 6x - 8 + 3x + 7 + 5x - 3
P = 14x - 4
Complex roots occur as conjugates so the other root is 3 + 2i
so we have the factored form
(x - (3 - 2i)(x - (3 + 2i)
= (x - 3 + 2i)(x - 3 - 2i)
= x^2 -3x - 2ix - 3x + 9 + 6i + 2ix - 6i- 4i^2
= x^2 -6x + 9 + 4
= x^2 - 6x + 13 Answer
