2. sqrt56x^2 = sqrt4*14*x^2 = 2x sqrt14 LETTER B
3. sqrt250h^4k^5 = sqrt 25*10*h^4*k^4*k = 5h^2k^2 sqrt10k LETTER C
4. sqrt15y * 3sqrt81y = sqrt15y * 27sqrt y = 27sqrt15y^2 LETTER C
58=y=39
(subtract 39 from both sides)
58-39=y
(simplify 58-39 to 19)
19=y
(switch sides)
y=19
Answer:
34 Using only the values given in the table for the function
Step-by-step explanation:
Answer:
25.) Slope of AB = 5
Slope of CD = -1/5
Perpendicular
26.) Slope of EF = -3/5
Slope of GH = -3/5
Parallel
Step-by-step explanation:
Use this formula to find slope. ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
Parallel lines have the same slope
Perpendicular lines have the opposite reciprocal and sign
25.)
Plug in AB slope is 5
2 - 7/ 3 - 4 = -5/-1 = 5
Plug in for CD slope is -1/5
3 - 4/ 2 - -3 = -1/5 = -1/5
The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.
26.)
Plug in EF slope is -3/5
1 - 4/ 3 - -2 = -3/5 = -3/5
Plug in GH slope is -3/5
-5 - -2/ 4 - -1 = -3/5 = -3/5
The lines EF and GH are parallel lines because they have the same slopes.
Hope this helps ya!
Answer:
72 cm
Step-by-step explanation:
It would be multiplied by 8 so the length would become 72 cm
