(x+2)(x-8)is the answer
Aleonysh [2.5K]2 years ago
3 0

Answer:

x = - 8, x = 2 are the solutions

Step-by-step explanation:

Given

x² + 6x - 16 = 0

Consider the factors of the constant term (- 16) which sum to give the coefficient of the x- term (+ 6)

The factors are + 8 and - 2 , since

8 × - 2 = - 16 and 8 - 2 = + 6 , thus

(x + 8)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x - 2 = 0 ⇒ x = 2

Find the value of x to the nearest tenth.<br> tan 34° = 20
Likurg_2 [28]

Answer:

The value of x = 13.5.

Step-by-step explanation:

<u>In this question x is missing.</u>

<u>So, the question would be:</u>

<u>tan 34° = x/20.</u>

Now, to find the value of x:

tan 34 = \frac{x}{20}

\frac{x}{20} = tan 34

Multiplying both sides by 20 we get:

x=tan 34\times 20

On simplifying both sides we get:

x=13.49

So, to get the value of x=13.49 to nearest tenth is 13.5. As we see in hundredth place it is 9 and 4 in tenth place, so after rounding to tenth place 4 will change to 5 so the value is 13.5.

Therefore, the value of x = 13.5.

If 50 percent of x=66 then x =
sasho [114]

Answer:

132

Step-by-step explanation:

50 % means half

so 66 is half of whatever x is.

to find x you have to multiply 66 by 2 or add 66 to 66 which will give you 132 either way.
