Answer:
14
Step-by-step explanation:
PLUG 8 in for n. Use the order of operations to evaluate. 26-3(8+8)/4=
becomes: 26-3(16)/4=; multiply 3 x 16 = 48, use order of operations to divide 48/4=12. Then problem becomes: 26-12 = 14.
Congruent means they are the same size
To prove the two triangles are congruent you would need to know the length of at least two of the sides. If two sides were not known you would need to know the length of one side and at least one of the unknown angles.
Answer:
P = 12x - 9
Step-by-step explanation:
To find the perimeter of the triangle, we just add all of the sides.
The formula is:
P = a + b + c
Given:
a = 5x - 6
b = 4x - 3
c = 3x
Work:
P = a + b + c
P = 5x - 6 + 4x - 3 + 3x
P = 12x - 9
Answer:
neither can be a factor
Step-by-step explanation:
If (x -a) is a factor, then value of the function will be zero at x=a. Here, the function has a value of zero (x-intercept) at x = -1 and x = 3. Hence (x+1) and (x-3) are factors, but (x+2) and (x+4) are not. The function is non-zero at x=-2 and x=-4.
