Answer:
True for all values of a, b and c.
Step-by-step explanation:
(a–3c)(4c+2a)+3c(a+3c)=(2a–c)(3c+5a)–8a^2
Left side:
(a–3c)(4c+2a)+3c(a+3c)
= 4ac + 2a^2 - 12c^2 - 6ac + 3ac + 9c^2
= 2a^2 + ac - 3c^2
Right side:
(2a–c)(3c+5a)–8a^2
= 6ac + 10a^2 - 3c^2 - 5ac - 8a^2
= 2a^2 + ac - 3c^2.
So we see that the left side is identical to the right side so it is true for all values of the variables.
Answer:
A=202
Step-by-step explanation:
A=2(wl+hl+hw)
2·(13·5+2·5+2·13)=202
Answer:
Step-by-step explanation:
Given that Rafaela is a physical education teacher and has 25 girls and 35 boys in her class.
She wants to divide the class into teams of the same size, where each team has the same number of girls and the same number of boys. If Rafaela creates the greatest number of teams possible, how many boys will be on each team?
Here we find Highest common factor for 25 and 35 and it is 5
So 5 boys will be on each team (with 7 girls)
2) length I = 7m, x12 m and height = 3mx85 cm.
The longest tape would be the highest common factor of 12 and 85
Since it is 1, only 1 cm long tape can be used.
