identify the mistake that was made simplifying the expression. then correctly simplify the expression.

5(a+7) - 3(2a+3) - 3a
5a + 35 - 6a + 9 - 3a
(5a - 6a - 3a) + (35 + 9)
-4a + 44

Step-by-step explanation:

The mistake is in 2nd step . There should be - 9

Correct :

5a + 35 - 6a - 9 - 3a

-4a + 26

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
