Answer:
(w² + 6)(w² - 6)
Step-by-step explanation:
difference of squares
w⁴ - 36 = (w² + 6)(w² - 6)
Answer:
3x² - 14x + 14
Step-by-step explanation:
Given
3(x - 2)² - 2(x - 1) ← expand (x - 2)² using FOIL
= 3(x² - 4x + 4) - 2(x - 1) ← distribute both parenthesis
= 3x² - 12x + 12 - 2x + 2 ← collect like terms
= 3x² - 14x + 14
There is no ones place after the decimal so 3 is in the tenth place, so 2.4
Answer:
58
Step-by-step explanation:
Ok So do you see the right angle square that equals 90 so all you have to do is subtract 32 from 90 which is 58
Answer:
C
Step-by-step explanation:
If you fill in x=0, you are left with the y intercept. In the picture you can see it must be larger than y=10. This invalidates answer A and D.
The x-coordinate top of the parabola ax²+bx+c=0 is given by y = -b/2a, so immediately we can see -b has to be positive. This leads you to answer C because -9x implies b=-9, and --9 is positive.
