3 (3+4k)=45 can you help me with this one

3 (Please give brainliest if it helped!)

Step-by-step explanation:

9+12k=45

12k=36

k=3

Let's solve your equation step-by-step.

3(3+4k)=45

Step 1: Simplify both sides of the equation.

3(3+4k)=45

(3)(3)+(3)(4k)=45(Distribute)

9+12k=45

12k+9=45

Step 2: Subtract 9 from both sides.

12k+9−9=45−9

12k=36

Step 3: Divide both sides by 12.

12k/12 = 36/12

k=3

k=3

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
