The perimeter of a triangle with length of sides a, b and c:
P = a + b + c
a = 2, b = 5, c = 10x
Substitute:
P = 2 + 5 + 10x = 7 + 10x
<h3>Answer: 7 + 10x</h3>
The smaller angle is 60 degrees and the larger angle is 120 degrees.
x+2x = 180, 3x=180, so x = 60 and 2x = 120.
Answer:
The area of A is nine times the area of B.
Step-by-step explanation:
Answer:
should be easy just plot the points
Step-by-step explanation:
we don't have the chart, though.
X ^2 +6x+ 5
(x+2)(x+3)
2 + 3 = 5
While also 2•3= 6
The two numbers have to equal b when multiplied and c when added
