Answer:
Perimeter: 26 units
Area: 24 units²
Step-by-step explanation:
12 + 9 + 5 = 26
A = 1/2BH
A = 1/2 12(4)
A = 1/2 48
A = 24
Answer:
Cynthia = 12 guavas
Bessy = 36 guavas
Aicel = 72 guavas
Step-by-step explanation:
Total guavas = 120
Let
Cynthia = x
Bessy = 3x
Aicel = 2(3x)
= 6x
x + 3x + 6x = 120
10x = 120
x = 120/10
x = 12
Cynthia = x
= 12 guavas
Bessy = 3x
= 3(12)
= 36 guavas
Aicel = 6x
= 6 × 12
= 72 guavas
Total = 74 + 36 + 12
= 120 guavas

Step-by-step explanation:
X - 3 < = 5 x < = 5 + 3 x < = 8 closed circle on 8 (it is closed because there is an equal sign in the problem)...and since it is less then, it will be shaded to the left.
