Given that:
(x+2)(2x-5)=54
We have:
Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.
Answer: 4 and 7.5 you multiply them
Step-by-step explanation:
Answer:
C) Jo's drink will have a stronger orange taste
Step-by-step explanation:
tropical punch calls for 2 liters of pineapple juice and 3 liters of orange juice.
total is 2+3 = 5 liters
pineapple = 2/5
orange = 3/5
Jo creates a drink by mixing 3 liters of pineapple juice with 4
total = 7
pineapple = 3/7
orange = 4/7
Get a common denominator to compare
5 and 7 = 35
tropical punch
pineapple = 2/5 *7/7 = 14/35
orange = 3/5*7/7 = 21/35
Jo
pineapple = 3/7*5/5 = 15/35
orange = 4/7*5/5 = 28/35
Jo will have both a stronger pineapple and orange taste than the tropical drink and the orange will be stronger than the pineapple in her drink
Answer:
5
Step-by-step explanation:
because 4/5=0.8
and 5×0.8 = 4
Step-by-step explanation:
Here, f(x) is the given polynomial.
By remainder Theorem,
When divided by (3x-1),
f(1/3) = -3........(1)
When divided by (x+1),
f(-1) = -7.........(2)
<em>Another</em><em> </em><em>polynomial</em><em> </em><em>is</em><em> </em><em>3</em><em>x</em><em>²</em><em>+</em><em>2</em><em>x</em><em>-</em><em>1</em>
Solving,
3x²+2x-1
= 3x²+3x-x-1
=3x(x+1)-(x+1)
=(3x-1)(x+1)
So
f(x) = (3x-1)(x+1)Qx + (ax+b)
For f(-1),
-7 = -a+b
b= a-7
For f(1/3),
-3 = a/3+b
or, -3 = a/3+a-7
or, 4×3 = 4a
or a = 3
Also, b = 3-7 =-4
Hence, remainder is (3x-4)
