Is (x + 5) a factor of f(x) = x3 − 4x2 + 3x + 7?
Answers
Answer:
no
Step-by-step explanation:
here, f (x)=x^3 - 4x^2 + 3x + 7
when, factor is (x + 5)
x - a =x + 5
a = -5
Reminder= f (a)
= (-5)^3 - 4 (-5)^2 + 3×(-5) + 7
= -233
Since Reminder = -233 which is not 0 .
(x + 5) is not a factor of f (x)=x3-4x2+3x+7

Tom got on a scale while on a vacation in France and noticed he weighed 75 kg. He read in a guidebook that 1 lb. = 0.45 kg. How much does Tom weigh in pounds
Answers
Answer:
166.67 pounds
Step-by-step explanation:
Set up a proportion where x is Tom's weight in pounds:
[tex]\frac{75}{x}[/tex] = [tex]\frac{0.45}{1}[/tex]
Cross multiply and solve for x:
75 = 0.45x
166.67 = x
So, Tom weighs approximately 166.67 pounds

1.Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20. What are the least numbers of packs you should buy in order to have the same number of plates, utensils, and cups?
Answers
Answer:
Least no of packs = 120
Step-by-step explanation:
Given that,
Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20.
We need to find least numbers of packs you should buy in order to have the same number of plates, utensils, and cups.
It means we need to find the LCM of 8,12,20
Prime factorisation of 8 = 2×2×2
Prime factorisation of 12 = 2×3×2
Prime factorisation of 20=2×5×2
LCM = 120
Hence, there are 120 least number of packs you should buy in order to have the same number of plates, utensils, and cups

Answers
Answer:
thats only 25
Step-by-step explanation:
Explanation:
I’m assuming one of those measurements must be a width, so to find the area of a rectangle it is length x width.
So, it would be 8.96 in x 7.7 in, which gives you a squared unit (in2).

What is 1/2x1/2 in fractions?
Answers
The requried multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts.
To multiply fractions, you simply multiply the numerators together and the denominators together.
The multiplication of 1/2 and 1/2 is calculated as follows:
(1/2) * (1/2) = (1 * 1) / (2 * 2)
= 1 / 4
Therefore, the multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts, it's equivalent to multiplying 1/2 by 1/2.
