You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
Answer:
their sizes vary
Step-by-step explanation:
their sizes vary
78 units squared add together 27.5+12+22+16.5 and you’ll get your answer for triangles it’s 1/2bh and for the rectangles it’s just bh. hope this helped!
Let x be the length of the garden
and y be the width of the garden.
since you only enclose 3 sides of the garden by a 40 ft fence. so the equation for this is:
2x + y = 40
and the area of the garden is 100 sq ft, so in equation
xy = 100
from equation 1, 2x + y = 40
y = 40 - 2x
substitute to equation 2
xy = 100
x ( 40 - 2x) = 100
40x - 2x^2 = 100
2x^2 - 40x + 100 = 0
x = 2.9 ft
y = 34.5 ft
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
