Answer:

Step-by-step explanation:

Solve for o in the equation (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 41o(7 + 4)(1) = 7 + 41o(7 + 41) + ( - 7 - 41) = 0

We first need to simplify the expression removing parentheses

Simplify 41o(7 + 4): Distribute the 41o to each term in (7+4)

41o * 7 = (41 * 7)o = 287o 41o * 4 = (41 * 4)o = 164o

Our Total expanded term is 287o + 164o

Simplify 41o(7 + 41): Distribute the 41o to each term in (7+41)

41o * 7 = (41 * 7)o = 287o 41o * 41 = (41 * 41)o = 1681o

Our Total expanded term is 287o + 1681o

Our updated term to work with is (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 287o + 164o(1) = 7 + 287o + 1681o + ( - 7 - 41) = 0

We first need to simplify the expression removing parentheses

Simplify 164o(1): Distribute the 164o to each term in (1)

164o * 1 = (164 * 1)o = 164o Our Total expanded term is 164o

Our updated term to work with is (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 287o + 164o = 7 + 287o + 1681o + ( - 7 - 41) = 0

Step 1: Group variables: We need to group our variables (7 and 14©(7. To do that, we subtract 14©(7 from both sides (7 - 14©(7 = 14©(7 - 14©(7

Step 2: Cancel 14©(7 on the right side: 0o = 0 Step 3: Divide each side of the equation by 0

0o 0 = 0 0 o =

Write a quadratic equation with the solutions x=-5+sqrt 13/2 , -5-sqrt 13 /2 HELP please
QveST [7]

Answer:

If we used the quadratic formula to solve the equation we can say:

-b = -5

b² - 4ac = 13

2a = 2

Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:

25 - 4c = 13

Solving this we get c = 3 so the answer is x² + 5x + 3.

Dylan makes $336 for 32 hours of work, and Angela makes $420 for 42 hours of work. How much do Dylan and Angela each make per ho
lions [1.4K]

Answer: (first half) Dylan= $10.5 per hour

Angela$10 per hour

(second half) No because they have different rate as the one before


Step-by-step explanation:

step one : divied how much money they make by the number of hours

Dylan

$336/32 hours = $10.5 per hour

Angela

$420/42 hours = $10 per hour

Step two: multiply the answer you got for Dylan by 25 hours and Angela by 42

Dylan

10.5 (25) = $262.5

Angela

10 (42)= 420

(Rates)

Dylan rate before = $336

Rate after solving = $262.5

Angela rate before = $420

Rate after solving = $420


i hope this helps ;)
