Answer:
42.6cm
Step-by-step explanation:
The sum total of all the sides of the shape is the perimeter of the shape. Hence;
Perimeter = x+3 + 4 + x+9 + 2x+5
Perimeter = 4x + 21
Given
Area of the figure = 75cm^2
Area = (x+3)(2x+5) + (2x+1)(6)
75 = 2x²+5x+6x+15+12x+6
75 = 2x²+23x+21
2x²+23x+21-75 = 0
2x²+23x-54 = 0
x = -23±√23²-4(2)(-75)/4
x = -23±√529+600/4
x = -12±√1129/4
x = -12+33.6/4
x = 21.6/4
x = 5.4
Recall that;
Perimeter = 4x+21
Perimeter = 4(5.4) + 21
Perimeter = 21.6+21
Perimeter = 42.6cm
Hence the perimeter is 42.6cm
Hey, you didn’t provide any picture or further context.
To solve for gradient, do (y2-y1)/(x2-x1)
So what do you think?
Answer:
If the children divide evenly onto 3 buses, there will be 11 children on each bus
Step-by-step explanation:
Add all 3 classes to ind total amount of students
Ms. Noels class has 10 students
Mr. Grubbs class has 9 students
Ms. Ackerman's class has 14 students
<u>Total Students:</u> 10 students + 9 students + 14 students
33 total students
Dividing 33 students in 3 busses is 33 / 3 which equals 11
Starts with 5 then adds 6 repeatedly
No.Because 14/2=7 and 7*3=21 so $21 is the answer.
