Answer:
Step-by-step explanation:
A) 3x²c² + 5xc² - 2c²
Factor c² from all terms in the expression.
c²(3x² + 5x - 2)
Factor 3x² + 5x - 2
c²(3x-1)(x+2)
B) x² + 6x + 9
x² + 3x + 3x + 9
Factor common terms.
x(x+3)+3(x+3)
Take x+3 common.
(x+3)(x+3)
C) x² - 9
x² -3²
Apply formula : a² - b² = (a+b)(a-b)
(x+3)(x-3)
Substitute -1 for x
2(-1)+3=
-2+3=
1
answer is 1 because you subtract 3 from 2 and the answer is positive because 3 is higher than 2..if I were you I'd pick B
The answer is 5.6 km.
1000m=1km
5600m=?
5600/1000*1km=5.6km
Answer:
Rs. 4,200,000
Step-by-step explanation:
Given :
Volume of brick = 500cm³
Dimension of wall : 200m×0.5m×1.5m
Converting to cm
Volume of compound wall:
(200 * 100) * (0.5 * 100) * (1.5 * 100)
20000cm * 50cm * 150cm=
= 150000000cm³
Volume of compound wall / volume of brick
1500000000 cm³ / 500 cm³
= 300000
Price per brick = Rs. 14
Total price = 14 * 300000 = Rs. 4,200,000
