I need you to help me solve this

Svet_ta [14]

For the expression to be factor-able the Discriminant , has to be greater or equal to zero
ax^2 + cx + b = 0

c^2 - 4 ab >= 0

(-3)^2 - 4 * 1 * b >= 0

9 - 4b >= 0

9 >= 4b

b <= 9/4 (2.25)

Pick any value in that range for ex:

0 , 2, -3, -6

Oman said that it is impossible to raise a number to the power of 2 and get a value less than the original number. Do you agree

Eva8 [605]

Oman is wrong, if you raise any decimal number less than one to a power of 2 the number just gets smaller

PLS HELP ME 6, 7, and 8 (SHOW WORK!!) + LOTS OF POINTS + THANKS! + BRAINLIEST IF POSSIBLE!

6. $1 \frac{1}{2} = \frac{6}{4}$ since $\frac{1}{4} = 4$ feet. Then 6*4=24 So the answer is C

7. 1200 m/8 cm = C. 1 cm = 150 m

8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.

B. A=lxw so 16*12= 216 $m^{2}$

Hope that helps
