Answer:
91 cm^2
Step-by-step explanation:
The bottom rectangle has an area of
A = l*w = 5* 14 =70
The top right rectangle has an area of
A = 3 *7 = 21
Add the areas together
A = 70+21 = 91 cm^2
Answer:
x = -8
y = -10
Step-by-step explanation:
Elimination
2x - 3y = 14
5x - 3y = -10
__________--
-3x = 24
x = 24/-3
x = -8
Subsitution
2x - 3y = 14
2(-8) - 3y = 14
-16 - 3y = 14
-3y = 14 + 16
-3y = 30
y = 30/-3
y = -10
Given:
Triangular garden
smallest side: x
medium side: x + 5ft
largest side: 2x - 6ft
Perimeter: 47 ft.
Perimeter = smallest side + medium side + largest side
47 ft = x + x + 5ft + 2x - 6ft
47 ft - 5ft + 6ft = 4x
48ft = 4x
48ft / 4 = 4x / 4
12 ft = x
smallest side: x = 12 feet
medium side: x + 5ft = 12ft + 5ft = 17 ft
largest side: 2x - 6ft = 2(12ft) - 6ft = 24ft - 6ft = 18ft
Perimeter: smallest + medium + largest
47ft = 12ft + 17ft + 18ft
47ft = 47ft
