Answer:
41 units
Step-by-step explanation:
Rectangles have right angles, so we can use Pythagorean theorem to find the diagonal.
c² = a² + b²
c² = 9² + 40²
c² = 81 + 1600
c² = 1681
c = 41
Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.
Answer:
14.5
Step-by-step explanation:
12 13 14 15 16 17
X O ^14.5 is in the middle O X
Answer: x > 6
Step-by-step explanation: Since <em>x</em> is being multiplied by 7,
we divide by 7 on both sides of the inequality to get x > 6.
Now you should write your answer in set notation.
So we have {x: x > 6} which means that
any number greater than 6 is a solution.
X+8>14
Subtract 8 from both sides-
x>6
Do you need help with the graphing part too?
