Answer:
2 real solutions
Step-by-step explanation:
a=-10, b=-4, c=2
(-4)^2-4x(-10)x2=96
Answer:
16.3
Step-by-step explanation:
The tenth place is right after the decimal, afterwards, its hundredths and then thousandths. The number after the tenth's place is 8. Since the number is 5 and above, you round up and add 1 to the tenths place to get 16.3. If the hundredths was 4 and below it would round to 2.

X= brother's height
Multiply 2/3 by the brother's height (x). This equals the sister's 48 inch height.
2/3x= 48
divide both sides by 2/3
x= 48 ÷ 2/3
multiply by the reciprocal of 2/3
x= 48 * 3/2
x= (48*3)/2
x= 144/2
x= 72 inches, the brother's height
ANSWER: The brother is 72 inches tall.

Answer:
Step-by-step explanation:
The expression can be factored using the factors of 14, 2 and 7, which add to give 9.
x² -9x +14 = (x -2)(x -7)
One of the factors is (x -2).
