Answer:
Perimeter is 30 and area is 32
Step-by-step explanation:
7+8+7+8= 30 and A= BH so 8 x 4 = 32
- 1 < - x/3 < 1
1st. Multiply all parts by 3:
-3 < - 3x/3 < 3. Simplify the mid term:
-3 < -x < 3. Now multiply all terms by - 1. Note when you multiply by a negative number, you flip the inequality signs:
(-1)(-3) < (-1)(-x) < (-1)(3)
+3 > x> -3
57
2^2=4
4+4=8
6*8=48
48+9=57
Answer:
x = 40
Step-by-step explanation:
3x + (x+20) = 180
Answer:
