Answer:

The correct option is 2.

Step-by-step explanation:

The given expression is

7(x+3)

Distributive property: If a,b and c are three real values, then

a(b+c)=ab+ac

In the given expression a=7, b=x and c=3.

Using distributive property, the given expression can be written as

7(x+3)=7(x)+7(3)

7(x+3)=7x+21

The simplified form of given expression is 7x+21. Therefore the correct option is 2.

Determine the value of k for which -3x^2+12x+k=0 has no real roots. ​
Crazy boy [7]

Answer:

K<-12

Step-by-step explanation:

+ For that, we need the delta negatif.

+ The delta= b^2-4ac=12^2-4(-3)(k)=144+12k<0

Then, 12k<-144 (divise both sides by 12)

we have k<-12

Or an other way:

-3x^2+12x+k=0  (divise both sides by -3)

x^2-4x-k/3=0

x^2-4x+4 -4-k/3=0

(x-2)^2=4+k/3

Now , we need 4+k/3<0, k/3<-4 or k<-12

Hope you understand.

Is (-5,6) a solution for 4x + 3y = 9
ozzi

Answer:

No.

Step-by-step explanation:

Insert the x and y, (-5 is x and 6 is y) into the equation. It should look like 4(-5)+3(6)=9. 4(-5)=-20 and 3(6)=18. -20+18=2 not 9.

(hope this helps :P)
