We have to determine the equivalent factored form for the quadratic polynomial:
2 x² + x - 6
2 x² + x - 6 = 2 x² + 4 x - 3 x - 6 =
= 2 x ( x + 2 ) - 3 ( x + 2 ) =
= ( x + 2 ) ( 2 x - 3 ).
Zero pairs:
x + 2 = 0
x = - 2;
2 x - 3 = 0
2 x = 3
x = 3 /2
Answer:
The number of zero pairs needed to model this polynomial is : two ( x = - 2 and x = 3/2 ).
The equivalent factored form is: ( x + 2 ) ( 2 x - 3 ).
Answer:
V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.
Answer:
5 lbs
Step-by-step explanation:
1) x = lbs. of coffee at $7 per lb
2) (7)(x) + (4)(10) = (5)(x + 10)
3) 7x + 40 = 5x + 50
7x - 5x = 50 - 40
2x = 10
x = 5 (lbs. of coffee at $7 per lb.)
Hello!
To find the circumference you use the equation

r is the radius
Put 3.14 in for pi
2(3.14)(26.85) = 168.618
Round the the nearest tenth
The answer is 168.6
Hope this helps!
