Answer:
Step-by-step explanation:
11(143) = 11(100 + 40 + 3)
= 11(100) + 11(40) + 11(3)
9(821) = 9(800 + 20 + 1)
= 9(800) + 9(20) + 9(1)
3(937) = 3(900 + 30 + 7)
= 3(900) + 3(30) + 3(7)
6(342) = 6(300 + 40 + 2)
= 6(300) + 6(40) + 6(2)
5(209) = 5(200 + 0 + 9)
= 5(200) + 5(0) + 5(9)
Answer:
x² + 2ax + a² + 5x + 5a + 4
Step-by-step explanation:
Formula -
( a + b )² = a² + 2ab + b²
Steps -
( x + a )² + 5 ( x + a ) + 4
x² +2ax + a² + 5 ( x + a ) + 4
x² + 2ax + a² + 5x + 5a + 4
Answer:
There are infinite solutions because they are the same equation
2D + 1G = 12
and
4D + 2G = 24 (divide by 2) 2D + G = 12
2D + 1G = 12 is the same as 2D + 1G = 12
Answer:
I'm pretty sure it's
yes, yes, no, yes.
I've never had to do this so I'm sorry if I'm wrong
