Which of the following represents a first step in solving the equation (x - 6)² = 9?

Alik [6]

"B." Because you must do what's in the parenthesis first. So 6² is 36 so that would be x-36=9 then to solve it $x-36=9 \\ +36=x-9 \\ 9+36=45 \\ x=45$

Integer that describes debit of $40

Sladkaya [172]

Alright - we want to start off by seeing if this number would be positive or negative. Debit means that you owe something, or that you have to pay that amount of money. If you had money to buy things with, that would be positive, but since debit means you haven’t paid something off yet, that is negative. Next, since you have 40 dollars in debt, you have -40 dollars.

Use the figure below to complete the following problem. Given: H = 2x + 60 T = x + 30 HALT is a ∠H = 90 120 150

Pavlova-9 [17]

Answer:

∠H = 120

Step-by-step explanation:

See the attached figure

HALT is a parallelogram

So, angles H and T are supplementary.

∠H = 2x + 60 and ∠T = x + 30

∠H + ∠T = 180

∴ 2x + 60 + x + 30 = 180

∴ 3x + 90 = 180

∴ 3x = 180 - 90 = 90

∴ x = 90/3 = 30

So, ∠H = 2x + 60 = 2 * 30 + 60 = 60 + 60 = 120
