Answer:

7 and 11

Step-by-step explanation:

Suppose the numbers are x and y.

So it is given that

x + y = 18

x - y = 4

If we add the equations, we get

2x = 22

So x is 11 and y will be 7

Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

(x + 1) \\ x =  - 1

Now put its value (-1) in the polynomial

{x}^{3}  - 13 {x}^{2}  + 32x - 20

Now if the answer comes zero it is a factor.

You'll get your answer!

the following equation represents the total distance (d) that the Benson family has traveled from their home, after traveling 10
Pani-rosa [81]

Answer:

The distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents  292.5 miles

Step-by-step explanation:

The given equation for the distance the Benson family traveled from their home can be presented as follows;

d = 55·t + 100

Where;

d = The total distance that the Benson family has traveled from their home after traveling 100 miles to pick up their grandparents

t = The time duration the Benson family have been traveled from their grandparents home on the way to their vacation

To find how far from their home the Bensons will be after 3 1/2 hours of driving with their grand parents, we substitute t with 3 1/2 hours or 3.5 hours as follows;

d = 55·t + 100

When t = 3\frac{1}{2} hours, we get;

d = 55 \times 3\frac{1}{2} + 100 = 292.5  \ miles

Therefore, the distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents = 292.5 miles.

Is the product of two prime numbers a prime number or a composite<br> number?
abruzzese [7]

Step-by-step explanation:

No, the product of two (or more) prime numbers cannot result in another prime number. By definition, a prime number is a number that is divisible by 1 or itself - the act of multiplying two or more primes together will always yield a number divisible by 1, itself and the prime numbers multiplied together to achieve it.
