-3(3x-5y-9) that’s the factored expression
Answer:
Because they are supplementary angles, their sum is 180°.
∠b = 180° - 81°
∠b = 99°
<em>q(x)=8x-7</em> is your equation.
When x = 4
Plug in 4 for x
q(4) = 8(4) - 7
Follow PEMDAS. Multiply 8 with 4
q(4) = 32 - 7
Subtract
q(4) = 25
(D) 25 is your answer

Answer:
x = 4.65 or x = -0.65 (to 2 d.p)
Step-by-step explanation:
To complete the square, use the formula x² + bx + c = (x + b/2)² - (b/2)² + c
- In this case, x² - 8x - 32 = (x - 4)² - 16 - 32
- This simplifies to (x - 4)² - 48 = 0
To solve this:
- First, add 48 to both sides → (x - 4)² = 48
- Next, square root both sides → x - 4 = ± √48 (remember that the square root of a number always has a positive and negative value)
- Finally, add 4 to both sides → x = 4 ± √7
x has 2 solutions
x = 2 + √7 or x = 2 - √7
x = 4.65 or x = -0.65 (to 2 d.p)
Hope this helps!
According to my calculations the 1.37 x 108 can not be past 35km because that is beyond or less than the universe we will all die sooner or later or in years or days or months so 1 2 3 4 - 5 + 2 x 5x 82 136- - 5347 + = e.140071763947832. 7 x 10
