What is the missing term?​
Brut [27]

Answer:

Missing term = 6x

Step-by-step explanation:

We got:

=> 4x by multiplying +4 and x (x * 4 = 4x)

=> 12 by multiplying +4 and +3 (4 * 3 = 12)

=> 2x² by multiplying 2x and x (2x * x = 2x²)

Similarly we will get the "missing term" by multiplying 2x and +3

=> <u>Missing term = 6x, (2x * 3 = 6x)</u>

Hope this helps!

What value of a makes the solution to the equation 5x-10=3x+a equal to 12
Illusion [34]

Answer:

a=-1.2

Step-by-step explanation:

5x-10=3x+a=12

let's first find x:

5x-10=12

add 10 to both sides:

5x=22

divide both sides by 5:

x=4.4

now that we know what x is, we can plug it back into the equation to find a:

3*4.4+a=12

first, simplify both sides:

13.2+a=12

then, subtract 13.2 from both sides:

and our answer is: a=-1.2
