Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
NUMBER ONE IS THE RIGHT ANGLE AND THE SECIND INE IS SUPPLEMENTARY
x=2y-2
x=y+3
Substitute the second equation into the first
y+3=2y-2
solve for y
y=5
plug into original
x=y+3=5+3=8 or x=2(5)-2=8
Allentown got 8 ft of snow, Georgetown got 5 ft of snow.
Answer:
x=35/78
Step-by-step explanation:
3/2x-11/5=(7/8)*(64/49)
3/2x-11/5=8/7
3/2x=8/7+11/5
3/2x=117/35
x=(35*3)/(2*117)
x=35/78
Answer:
x^2+14x+49 ( it could be polynomial because it has 3 terms and each term has a whole number and a coefficient)
Step-by-step explanation:
(x+7)^2
(x+7)(x+7)
x^2+7x+7x+49
x^2+14x+49
I am not sure it's a polynomial or not
