Same as what I explained in your last question.
840, base, perimeter.
Hope this helps!!!
Thanks for using Brainly!
X + y = 5
xy = 12
x + y = 5
y = -x + 5
xy = 12
x(-x + 5) = 12
x(-x) + x(5) = 12
-x² + 5x = 12
- 12 - 12
-x² + 5x - 12 = 0
x² - 5x + 12 = 0
x = 5 ± √25 - 48
2
x = -5 ± √-23
2
x = -5 ± 4.79i
2
x = -5 + 4.79i or x = -5 - 4.79i
2 2
x = -2.5 + 2.395i or x = -2.5 - 2.395i
y = -2.5 - 2.395i or y = -2.5 + 2.395i
The two numbers that add up to 5 and multiply to 12 is -2.5 ± 2.395i, which is -2.5 + 2.395i and -2.5 - 2.395i.
Answer:
9
Step-by-step explanation:
Points R, S, and T are collinear.
RT = x + 5
ST = 4x - 9
RS = x - 2
First, create an equation to find the value of the variable x
RS + ST = RT (segment addition postulate)
(x - 2) + (4x - 9) = (x + 5) (substitution)
Solve for x
x - 2 + 4x - 9 = x + 5
Collect like terms
5x - 11 = x + 5
5x - x = 11 + 5
4x = 16
Divide both sides by 4
4x/4 = 16/4
x = 4
RT = x + 5
Plug in the value of x
RT = 4 + 5
RT = 9
Answer:
Therefore the Expression will be.
...As minus - minus sign becomes plus.
Step-by-step explanation:
What is six minus negative two x?
Solution:
It is the Algebraic Expression in Statement form.
Algebraic Expression is given in the form numbers and variables with the operands such as
- ' + ' Plus Sign
- ' - ' Minus Sign
- ' × ' Multiplication Sign
- ' ÷ ' Division Sign, etc.
Hence Our Statement is " six minus negative two x "
i.e. Number 6 minus sign then again a minus sign of 2x.
Therefore the Expression will be.
Also equals
...As minus - minus sign becomes plus.
