Answer:
see below
Step-by-step explanation:
3x^2 + 17x +10 =0
(3x+ ) ( x+ ) =0
We need to factor 10 = 2*5 or 1*10
They are positive since we have all positive terms
3*5 = 15+2 = 17
The 5 needs to multiply the 3 so it goes on the outside
(3x+ ) ( x+ 5 ) =0
That leaves the 2 on the inside
(3x+ 2 ) ( x+ 5 ) =0
Using the zero product property
3x+2 =0 x+5=0
3x = -2 x=-5
x = -2/3 x = -5
A right triangle must satisfy this equation: a^2 + b^2 = c^2
a= shortest length
b=medium length
c=the longest length
a triangle with sides 4,5,6 will satisfy not this equation because:
4^2 + 5^2 ≠ 6^2
16+25 = 41
41 ≠ 36
so the answer is C.

or >11-9 or >2
so third side=15 cm
Let x be the sale.
Then 500+.05x>1500
.05x>1500-500
.05 x>1000
x>$2000
minimum sale=$2000
Answer:
Rs. 10,100
Step-by-step explanation:
Sale price = 8820
Amount Lost on sale = 1280
The cost price of the camera:
Amount at which camera was sold + amount lost at that sale price
Rs. 8820 + Rs. 1280
= Rs. 10,100
Hence, cost price of camera was Rs. 10,100
