Answer: r= G/dh
Step-by-step explanation:
G= rdh
For r divide dh both sides
G/dh = rdh/dh
G/dh = r
Square and quadrilateral!
Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
