Answer:
I think is 12x2 +48x-27 but I'm confused
23, 879 to the nearest thousand.
The thousand digit is the 3, and we look at the digit after 3, which is 8, since 8 is more than 5, we round up the 3 to 4.
Therefore 23, 879 to the nearest thousand ≈ 24, 000
I hope this explains it.
I'd go with your third option, 6.
Half the diameter (the radius, also the hypotenuse for the right triangle) is 10 units.
Half of the chord given by that blue line segment is 8 units. Now we do the Pythagorean Theorem (a² + b² = c²) to find the length of x.
x² + 8² = 10²
x² + 64 = 100
x² = 36
√x² = √36
x = 6
we can write "m more than t" like this:
A=1/2 × (a+b) × h
=1/2 × (45+37) × 6
=1/2 × 82 × 6
=246mm^2
I hope this helps.
