Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. <u>12 units</u> = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. <u>1 unit </u>= 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm
Answer:
Step-by-step explanation:
c
Simple interest=Principal*Rate*Time
31=420*R*2.5 years
r =2.95%
Annual rate of interest=2.95%
2y^3+4y^3 is 6y^3
-7y^2+10y^2 is 3y^2 ***NOTE: 10y^2 is from the 6y^2+4y^2
-7y+3y is -4y
Answer: 6y^3+3y^2-3y
