Answer:
x^2 - 9x + 20
Step-by-step explanation:
(x - 4)(x - 5) (have to do the opposite for it to be positive)
FOIL method: X x X = x^2
-5 x X = -5x
-4 x X = -4x
x^2 - 5x - 4x + 20
-5 - 4 = -9 so...
x^2 - 9x +20 is the answer
3/4 (x-12)=12
3/4x - 9= 12
+9 +9
3/4x=21
*3/4 *3/4
x= 15 3/4
and
3/4y-12=12
+12 +12
3/4y = 24
*3/4 *3/4
y= 18
Answer:
2x² - 3x - 2
Explain:
Use the FOIL method: (a +b)(c +d) = ac + ad +bc +bd.
2x² + x - 4x - 2
Collect like terms.
2x² + (x - 4x) - 2
Simplify.
2x² - 3x - 2
The second one is the correct equation. The constant to the right should be the diameter squared, while the numbers inside the parentheses should be the opposite.
