Answer:
=10x2−8
Step-by-step explanation:
4(x2−5)+2(3x2+6)
Distribute:
=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)
=4x2+−20+6x2+12
Combine Like Terms:
=4x2+−20+6x2+12
=(4x2+6x2)+(−20+12)
=10x2+−8
what about this picture/function/expression?
well, we have 3 points over the y-coordinate, but but but, every point has the same x-coordinate, whatever that might be, and so they form a vertical line.
does this straight vertical line pass the vertical line test? nope.
other way to see it is, a function has no x-repeats, the x-coordinate for every point must not be repeated, in this case it is the same for all, so it repeats thrice, so is not a function, just a relation.
Answer:
4
Step-by-step explanation:
Radius = 1/2 Diameter
Diameter = 12
Radius = 6
Area of circle = (pi) r ^2
=pi 6^2
=36pi
Area = 113.1 cm^2
Answer:
look below
Step-by-step explanation:
well since it's a triangle you could find the the area then
you already know three measurements so you'd be able to find the surface area of the triangular prism
I hold I could help you ☺️
