17.4 x 1.0 Will the product be less than 17.4, equal to 17.4, or greater than 17.4? 17.4 × 0.98 Less than 17.4 Equal to 17.4 Gre
nikdorinn [45]

Answer:

1) Equal to 17.4

2)Less than 17.4

Step-by-step explanation:

One thing we must always remember that when we have number 0 after the decimal point, it means we do not need to consider that as it will have no effect on product and on the other operations.

So,

1)

17.4 x 1.0 = 17.4 x 1 = 17.4  (Product is equal to 17.4)

2)

Suppose if a number 'A' which is less than 1 is multiplied by any other number 'B', than the multiplication always result in the number less than B.

For example:

1x0.5 = 0.5 which is less than 1

Similarly for

17.4 x 0.98 = Result will be less than 17.4 as the second number is less than 1.

Product is less than 17.4

Solve the equation by completing the square. Round to the nearest hundredth if necessary? X^2+3x=24
Genrish500 [490]
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides

In this case (3/2)^2=2.25

x^2+3x+2.25=26.25 now the left side is a perfect square...

(x+1.5)^2=26.25  take the square root of both sides

x+1.5=±√26.25  subtract 1.5 from both sides

x=-1.5±√26.25

x=-1.5-√26.25 and -1.5+√26.25

x≈ -6.62 and 3.62

****Brainliest to best answer!!***<br> Thank u to everyone who helps!
Dmitrij [34]

Answer:

A

Step-by-step explanation:

When you read the question it says that her average speed from the library to the gym is 15 mph less than her speed from her home to the library. So x - 15 is what describes that situation.

If it is A it cannot be anything else.

B is incorrect. x - 15 is not a time. It is a rate. It can be used to develop the amount of time, but by itself it is still A.

C is incorrect. Her average speed from her house to the library is x

D is incorrect. The distance is given as the same as from her home to the library as  from the library to the gym. Both are 4
