Answer:

Area = 3x^5+3x^4-3x^3-3x^2

Step-by-step explanation:

Area equals length times width

x(x+1) * 3x(x^2-1)

(x^2+x) * (3x^3-3x)

3x^2(x+1)(x^2-1)

3x^5+3x^4-3x^3-3x^2

tamaranim1 [39]

X= number of student tickets

Y= number of on student tickets

x+y=311

0.50x + 1.50y = 385.50


Solve x in 1st equation


X+y=311


X= -y + 311


Now substitute x into second equation to solve for y


0.50(-y+311)+ 1.50y = 385.50


-0.50y+311.50+1.50y=385.50

Y+311.50=385.50


Y= 385.50-311.50


Y= 74


Now substitute y answer to first equation to find x


X+y=311


X+ 74=311


X= 311-74


X= 237


So 237 students tickets and 74 non students tickets

Step-by-step explanation:

believe it or not, the area of any triangle is

baseline × height / 2

we have here 2 triangles, both with the same baseline (8 cm), but with 2 different heights : 6.5 cm and 4.6 cm.

so, their areas are

8 × 6.5 / 2 = 4 × 6.5 = 26 cm²

8 × 4.6 / 2 = 4 × 4.6 = 18.4 cm²

so, in total, the shaded region is

26 + 18.4 = 44.4 cm²

Aicel,Bessy,Cynthia went to the farm to pick guavas. They picked 120 guavas in all. Aicel picked twice as many as Bessy did and
LenaWriter [7]

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
