Multiply 250 by 120 and the answer is 300,000ft2
Answer:
130
Step-by-step explanation:
Answer:
(x+3)²-11=0
Step-by-step explanation:
0=9(x2+6x)-18
0= 9x² +54x-18
0= 9( x²+6x-2) taking 9 common
0= x² +6x-2 (breaking the mid term to find the second element of the square
0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element
0= (x+3)² -11 summing up
7/100
3/10
21/125
3/ 2500
7/50
I simplified them for you
4X-4Y>28
X-Y>7 both side divide by 4
