Answer:

160 km

Step-by-step explanation:

The speed is equal to x distance over time, so to find distance you would multiply the speed by the time to tell you that 40 km per hour times 4 hours is equal to 160 km after the 4 hour time period.

Or in simpler terms, 40×4=160.

Hope this helped.

PLEASE HELPP PLEASE find the zeros and factored form of c(x)=3x^2-3

Zepler [3.9K]

Answer:

3 ( x-1) (x+1) is the factored form

zeros are x=1, -1

Step-by-step explanation:

3x^2-3

Factor out a 3

3 ( x^2 -1)

What is inside the parentheses is the difference of squares

( a^2 -b^2) = ( a-b)(a+b)

3 ( x-1) (x+1)

To find the zeros, set this equal to zero

3 ( x-1) (x+1) =0

Using the zero product property

x-1 =0 x+1 =0

x=1, x=-1

(a+b)2 ;a=1/2 and b=2

FrozenT [24]

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$ , thus

(a + b)² = ( $\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$
