Answer:
See below
Step-by-step explanation:
Do you mean -12(x+5)=-10?
Divide both sides by -12 -> x+5=10/12
Subtract 5 on both sides -> x=10/12-5 -> x=-4 1/6
So x=-4 1/6
Let me know if this wasn't the right equation
Answer: C) x = 2
2^{2x + 2} = 2^{3x}
Since both terms (above) have the same base, set the exponents to be equal:
2x + 2 = 3x (Rearrange to solve for x)
x = 2
∴ x = 2
Answer:
Gradient is change in y over change in x.
gradient = y1-y2 ÷ x1-x2
=7-11 ÷ 3-5
=-4 ÷ -2
=2
Answer:

Step-by-step explanation:

To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x
<u>NB</u><u>:</u><u> </u> Absolute value of a negative number is the same number but positive.
So we have

For downstairs- 28 x 38= 1064
For upstairs- 26 x 14= 364
All together- 1064 + 364= 1428
So.... 1428 seats in total.
Hope this helped! :)
