Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
Answer:
it's 25 cm
Step-by-step explanation:
Volume = 225π
or πr²h= 225π
or r²h= 225
or h= 225/r²
here diameter d = 6cm so radius r=d/2 = 3cm
or h= 225/3²
hence h= 25cm
Well 2÷1/2 is 4 and 4×3/4 is 12/4 which is also 3 whloes
Answer:
4x + 15
Step-by-step explanation:
A = 14x + 5[6 - (2x + 3)]
= 14x + 5[6 - 2x - 3]
= 14x + 30 - 10x - 15
= (14x - 10x ) + (30 - 15)
= 4x + 15
