2x^2 + 8x + 8
= 2(x^2 + 4x) + 8
= 2 [ (x + 2)^2 - 4) + 8
axis of symmetry is x = -2 ( because of the (x + 2)^2 )
Answer:
2x + 3x = 17.
$3.40.
Step-by-step explanation:
All the cones cost the same. That means that one ice cream cone will cost x dollars.
She spent $17, with 2 chocolate and 3 vanilla.
2x + 3x = 17
5x = 17
x = 17/5 = 3.4
So, each cone costs $3.40.
Hope this helps!
Percentage ridden = 14/40 x 100 = 35%
Answer: 35%
No, a triangle cannot have more than one obtuse angle. Obtuse angles are bigger than 90 degrees but smaller than 180 degrees. Pretend we had two obtuse angles both measuring 135 degrees and an acute angle measuring 23 degrees.
135 + 135 + 23 = 293
therefore, it wouldn't be a triangle anymore... a triangle only equals up to 180 degrees.
I hope that helps.
Joan: 12 years old
Amber: 22 years old
If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)
