Answer: y= - ( x - 5) ( x + 7)

Step-by-step explanation: The x-intercepts are at -5 and 7. when you don’t have a negative symbol before the parentheses, that indicates that the parabola will be shaped like a U. when you do, it’s shaped the opposite of a U. and now look at the equation answer.

Probability helps us to know the chances of an event occurring. The correct option is A.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

Dependent events are those events in which the outcome of the first event affects the outcome of the second event. The statement that is correct about the dependent event is that the probability of all dependent events can be calculated using the "OR" formula P(A+B) =P(A) +P(B)-P(A and B).

Hence, the correct option is A.

Examine the figure below.
goldfiish [28.3K]

The correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C

<h3>How to determine the angle</h3>

Given that;

∠ K =  (4x + 5)°

∠ J = 6x + 1

∠ L = 8x + 30 = 180 ( angles on a straight line)

Note that the sum of the angles of a triangle is 180°

∠ K + ∠ J  + ∠ L = 180

6x + 1 + 4x + 5 + 8x + 30 = 180

collect like terms

18x = 180 - 36

18x = 144

Make 'x' the subject

x = 144/ 18

x = 8

Substitute the values

∠ JKL = (4x + 5)° = 4(8) + 5 = 37°

∠KJ L  = (6x + 1)° = (6(8) + 1) = 49°

∠ KLM = 8x + 30 = 8(8) + 30 = 94°

∠ JLK = 8x + 30 = 180 = 180 - 94 = 86°

Thus, the correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C

What's the answer for (2+i)(i+2i)?​
slava [35]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{3 {i}^{2}  + 6i}}}}}

Step-by-step explanation:

\sf{(2 + i)(i + 2i)}

Use the distribute property to multiply each term of the first binomial by each term of the second binomial.

⇒\sf{2(i + 2i) + i(i + 2i)}

⇒\sf{2i + 4i +  {i}^{2}  + 2 {i}^{2} }

Collect like terms

⇒\sf{3 {i}^{2}  + 6i}

Hope I helped!

Best regards!
