Answer:
3√41
Step-by-step explanation:
The diagonal can be gotten using the pythagoras theorem
d² = l²+w²
d² = 12²+15²
d² = 144 + 225
d² = 369
d = √9*41
d = 3√41
Hence the diagonal is 3√41
The altitude is 6/4 but originally it’s 16 hope this helps ;)
Answer:
1
Step-by-step explanation:
Solve the equation for x:
3(x + 5) = -4x + 8
<em>Distribute.</em>
3x + 15 = -4x + 8
<em>Combine like terms.</em>
3x + 15 = -4x + 8
+4x +4x
7x + 15 = 8
-15 -15
7x = -7
<em>Divide both sides by 7.</em>
x = -1
The following equation has one solution, x = -1.
The x-coordinate of the right-most point of S' is 4. In the original, it is 6. The dilation multiplier is 4/6 = 2/3.
Selection B matches that.
