A) area = length x width = 12 x 6 = 72 sq.cm
B) area = 1/2x base x height = 1/2 x 3 x 6 = 9 sq.cm
C) same as B= 9 sq. Cm
D) subtract area of both triangles from area of rectangle:
72 - 9 -9 = 54 sq. Cm
24/55 is the answer
You can either use a calculator on your phone or computer
Answer:
2 hours
Step-by-step explanation:
Each hour, Sam earns $9
So 2 hours, Sam will earn 2 * $9 = $18
Thus, Sam will earn $18 in 2 hours working at the drugstore.
Equ 1: X-Y=5
equ 2: x∗y=36
from Equ 1
X=5+Y------equ 3
substitute x=5+y in equ 2
(5+y)∗y=36
5y+y^2=36
y^2+5y-36=0
factorize by substitution
(y^2+9y)-(4y-36)=0
y(y+9)-4(y+9)=0
(y-4)(y+9)=0
y=4 or y=-9....
substitute y=4 or -9 in equ 1
x-4=5
x=5+4
x=9 OR
x-(-9)=5
x+9=5
x=5-9
x=-4
since -4∗-9=36
therefore y=-9 and x=-4
