Answer:
x = -2
TU = 4
UB = 2
Step-by-step explanation:
you can add x^2 with 4x+10 and equate it to 6:
x^2 + 4x + 10 = 6
x^2 + 4x + 4
then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a
so it'll be x = {-4±[√16 - 4(4)]}/2
x= -2
then u can substitute it and find TU and UB
TU= (-2)^2 = 4
UB= 4(-2)+10 = 2
Answer:
8 pieces
Step-by-step explanation:
To answer this we divide the total length of ribbon removed by -1.2.
-9 6/10 = -9.6
-9.6 / -1.2
= 8
Answer:
D. region B
Step-by-step explanation:
y has to be below the line y=x-2, that is region B and C
y has to be above the line y=x/4-4 that is region A and B
If y has to be both, only region B remains, which is answer D.
