Answer:
x = -2
Step-by-step explanation:
The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.
(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.
(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.
To find where it will touch the axis set the factor equal to zero and solve.
(x + 2) = 0
subtract 2 from both sides
x = -2
Answer:
21
Step-by-step explanation:
The sum of degrees in a triangle is 180, so we have:
3x+100+x-4=180
add 4 on both sides
3x+100+x=184
subtract 100 on both sides
3x+x=84
Combine like terms
4x=84
84/4 = 21

Answer:
n (aub)= n (a)+ n(b)
n (anb) = n (a)-n (b)
only a= n(a)+n(b) -(aub)
n only b= n (a)+n (b)-n (anb)
now solve your self because this formula help to solve
