Is there something missing on the third option? None of the other options are wider
Answer:
the answer to number one is (13.3,2)
the answer to number two is (2,-2)
Step-by-step explanation:
400/300 = 4/3 the water listed in the recipe
420g × 4/3 = 560g flour
21g × 4/3 = 28g salt
9g × 4/3 = 12g yeast
45ml × 4/3 = 60ml oil
Answer:
3y² -2y -1 =0
Step-by-step explanation:
X= y²+1 .....(1)
3x - 2y = 4.....(2)
put x in (2) : 3(y²+1
)-2y =4
3y² +3 -2y -4 = 0
3y² -2y -1 =0
Answer:

Step-by-step explanation:
The root of a polynomial: the value of which x makes f(x) = a,x^n+a₂x^n-1+...+aₙx+aₙ⁺₁=0
Because the polynomial has exactly 3 roots, we know that f(x) = (x+a) (x+b) (x+c)
(-a,-b and -c are the 3 roots)
So its highest digit is 3.
Only 2x³ - x² - x + 4 corresponds to it.
