Answer:
7/9y+441/567
Step-by-step explanation:
y^2-49/81y+567÷y-7/63
=y^2-49/81y+567×63/y-7
=(y-7)(y+7)/81y+567×63/y-7
=(y+7)×63/81y+567
=63y+441/81y+567
=7/9y+441/567
The way calculate the volume is l*w*h, 3 times 5 times 7 is 105
Answer: D. 105 km^3
First you find the area of the front face 1/2bh or in you case 10x12=120 1/2 of 120 is 60 next you multiply 60 by 20 to get 1,200 for the voulume
Answer:
16mm
Step-by-step explanation:
Just do 40 * 2/5 = 80/5 = 16mm
Given:
The graph of an inequality.
To find:
The inequality.
Solution:
In the given graph, the boundary line passes through the points (-3,3) and (0,1).
So, the equation of the boundary line is:




Adding 3 on both sides, we get


The boundary line is a solid line and the shaded region is above the boundary line. So, the sign of inequality must be
and the required inequality is:

Therefore, the correct option is B.
