A negative sign under a square root means that the root is a not a real number.
A negative sign outside a square root means we can "cover it" and evaluate the square root.
When the sign is outside, you can do the root first, then apply the sign. Not so if the sign is inside.
Thus, √-49 is not real and -√64 = -8.
Well the area of the triangle is 18 so Id figure if my math is correct x = 3
Answer:
x = 2
Step-by-step explanation:
If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
= = = 2 ( multiply both sides by x + 5 )
6x + 2 = 2(x + 5)
6x + 2 = 2x + 10 ( subtract 2x from both sides )
4x + 2 = 10 ( subtract 2 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Answer:
C.
Step-by-step explanation:
When you transfer 4% into a decimal, it equals 0.04, and p is the cost of a regular pizza, so you subtract 0.04 from p!
