Answer:
The answer is Option c
9, -12, 24
Step-by-step explanation:
We have the polynomial:
To find the zeros we must equal 
So:
Then the previous expression is equal to zero in any of these 3 cases:
<u>Case 1
</u>
<u>Case 2
</u>
<u>Case 3
</u>
Then if 
or 
or 
The answer is 9, -12, 24
Answer: 15(30 +33) = 945
Step-by-step explanation:
First, you have to distribute the 63 and make it smaller to become 30 + 33. So, the equation would be 15(30 + 33) = 450 + 495 = 945
Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10
Slope intercept form:
y = mx + c
Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6
Therefore, the equation is:
y = -10x + 6
Let x be the side of your square. Use Pythagoras to find the side in the right triangle formed with 2 sides and the diagonals:
x² + x² = 34²
2x² = 34² = 1126
x² = 1126/2 = 578
and x =√578 = 17√2 ≈ 24 ft
H will need 24 x 4 = 96 ft
