It is the plus minus sign. It means to do the addition and subtraction.
Examples:
10 <span>± 7 = 17 and 3
15 </span><span>± 5 = 20 and 10
100 </span><span>± 90 = 190 and 10
It is generally used to indicate a possibility of two outcomes. A negative or positive outcome.</span>
Xy = -112
x + y = -54
x + y = -54
2 + y = -54
- 2 - 2
y = -56
(x, y) = (2, -56)
or
x + y = -54
-56 + y = -54
+ 56 + 56
y = 2
(x, y) = (-56, 2)
The two numbers that multiply to -12 and add up to -54 are -56 and 2.
Answer:
The Volume is 660^3.
Step-by-step explanation:
The formula is Length * Width * Height.
22 * 5 * 6 = 660 and its volumed so the units is cubed.
Answer:
B
Step-by-step explanation:
because in the periodic table nitrogen is 7, and oxygen is 16
The value of x that will result for the rational expression to be undefined will be the values that will give 0 value for the denominator.
A. 7
<span>2(7)^2 -32 = 66
</span>
<span>B. 4
</span>2(4)^2 -32 = 0 <span>-------> undefined</span>
C. 2
2(2)^2 -32 = -24
<span>D. -2
</span>2(-2)^2 -32 = -24
<span>E. -4
</span>2(-4)^2 -32 = 0 -------> undefined
F. -7
2(-7)^2 -32 = 66
