a = $\sqrt{63}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 9² = 12²

a² + 81 = 144 ( subtract 81 from both sides )

a² = 63 ( take square root of both sides )

a = $\sqrt{63}$

Zigmanuir [339]

Answer:

Step-by-step explanation:

Job A:

Bonus of $1500
$120 per day for $d$ days is 120 multiplied by $d$ . Which is $120d$
Total Payment = $1500+120d$

Job B:

Bonus of $2500
$110 per day for $d$ days is 110 multiplied by $d$ . Which is $110d$
Total Payment = $2500+110d$

Solving these 2 equations for $d$ would tell us after how many days both job would pay the same. Answer choice C is correct.
