Answer:
Area = 88 m²
Perimeter = 44 m
Step-by-step explanation:
✔️Area of the shape = area of the rectangle + area of the square
Area of the rectangle = L*W
L = 12 m
W = 6 m
Area of rectangle = 12*6 = 72 m²
Area of the square = s²
s = 4
Area of the square = 4² = 16 m²
Area of the shape = 72 + 16 = 88 m²
✔️Perimeter = sum of the sides surrounding the shape = 12 + 6 + 4 + 4 + 4 + 4 + 4 + 6 = 44 m
Answer:
Step-by-step explanation:
2x + 3y = 6
y = x/3 - 3
Since the second equation is already solved for y, we can easily use the substitution method.
Substitute y in the first equation with x/3 - 3
2x + 3(x/3 - 3) = 6
2x + x - 9 = 6
3x = 15
x = 5
Now use the second equation, and x = 5, to solve for y.
y = x/3 - 3
y = 5/3 - 3 = 5/3 - 9/3
y = -4/3
Answer: (5, -4/3)
Answer:
w=4
Step-by-step explanation:
18+3w=30
3w=30-18
3w=12
w=4
$315, i cant give a thorough explanation since i did it all in my head but basically amal gets 5 portions of the money and Salma gets 9, meaning she gets 4 more, so if 4 portions is $252 then it cant be any of the others since they are too low or way too high, $315 is the only reasonable one.
