Answer:
64m^2
Step-by-step explanation:
(20 m + 8m) times 5 devided by 2 + (5 times 6) + (5 times 6) - ( 3 times 12) that gives you 64 m ^2
Answer: 3 hours and 25 minutes
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
R=3b
L=b+12
R= 3x6=18
L=6+12=18
If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.

For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
