Step-by-step explanation:
what is that X, and X²???
I wanna say 7 and 6 but I'm probably wrong
D.
(0) - 7 < 2(0) - 6
0 - 7 < 0 - 6
-7 < -6
-6 is higher than -7 which makes the inequality true.
Answer:
180 ft
Step-by-step explanation:
The perimeter of a geometric figure is the sum of the lengths of its sides. Opposite sides of a rectangle are of equal length, so the perimeter can be figured as twice the sum of the length of adjacent sides:
2(60 ft + 30 ft) = 180 ft
Mrs. Chen needs 180 feet of fence.
You can use the pythagorean theorem.

Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7

Now solve for x

x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
