The rule for side lengths of a triangle is that the two lowest lengths sum has to be greater than the longest length. so
a+b>c
For the 1st question
4+3>6
7>6
So yeah, it can be a triangle
For the 2nd one
1+3>4
4>4
So no, it can't be a triangle
Sandy has two possibilities
lengths of 3,3,4
or
lengths of 4,4,3

Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Multiply 200 rolls by 70%
200 *0.70 = 140
The bowler should knock at least 6 pins down 140 rolls
