Answer:
Answer B
Step-by-step explanation:
Since you're <em>dividing</em> -0.3 by -2.5, you are using the division property of equality.
Answer: x = -2
<u>Step-by-step explanation:</u>
A line perpendicular to y= (anything) is ....... x = ____
Since it must pass through a coordinate x = -2, y = 0
then the equation of the line is: x = -2
Answer:
900cm^2
Step-by-step explanation:
24, 10, 30 in half= 12, 5, 15 so, 12*5*15=900cm^2
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!
