The inequality X+C > -2.55 has the solution x> 4.85 What is the value of c? How do you know?
Answer:
The value for C is 2.3
in this case we know of x to be 4.85
therefore subtract the summation of both X+C from the value of x.
Hence we will have the equation X - X+C =2.3
Three consecutive integers have a sum of -42. Write and solve an equation to find the three integers.
x + ( x + 1 ) + ( x + 2 ) = -42
Opening the brackets and simplifying :
x + x + 1 + x + 2 = -42
3x + 3 = -42
Now , solving equation :
[tex]\bf \rightarrow \: \:3x \: + \: 3 \: = \: -42[/tex]
[tex]\bf \rightarrow \: \: 3x \: = \: -42 \: - 3[/tex]
[tex]\bf \rightarrow \:3x \: = \: -45 \: [/tex]
[tex]\bf \rightarrow \:x \: = \: \frac{ - 45}{ \: 3} \\ [/tex]
[tex]\bf \rightarrow \:x \: = \: \cancel\frac{ - 45}{ \: 3} \: \: ^{ - 15} \\ [/tex]
[tex]\bf \rightarrow \:x \: = \: - 15[/tex]
[tex]{\boxed{ \Large{ \red{ \rm{ \underline{ Now \: \: substitute}}}}}}[/tex]
[tex]\bf \implies \: \:x \: = \: - 15[/tex]
[tex]\bf \implies \: \:x \: + \: 1 \: = \: - 15 \: + \: 1 \: = \: - 14[/tex]
[tex]\bf \implies \: \:x \: + \:2 \: = \: - 15 \: + \: 2 \: = \: - 13[/tex]

Which is equivalent to the expression below?
3√3 + √6 + √12 - 2√3
A. 5√3
B. 3√3 + 6
C. 2√3 - √21
D. 5√3 - 6
Answer:
3√3 + √6 is the answer. so none is correct.
Step-by-step explanation:
= 3√3 + √6 + √12 - 2√3
= 3√3 + √6 + √4 X 3 - 2√3
= 3√3 + √6 + 2√3 - 2√3
= 3√3 + √6
Express 3x-2/(x-1)(x-2)
Answer:
3x-2/x²-3x+2
Step-by-step explanation:
you have to expand the bottom equations
(x-1)(x-2)
x(x-2)-1(x-2)
x²-2x-x+2
x²-3x+2
now from this you can't divide it into the top equation because not all the terms are like so it's better to bring it down as it is.
3x-2/x²-3x+2

which of the following expresses the possible number of positive real solutions for the polynomial equation shown below 5x^3 + x^2 +7x - 28 = 0
A. Two
B. Three or one
C. One
D. Two or zero
The possible number of positive real solutions for the given polynomial equation is; Option C; One
We are given the polynomial;
5x³ + x² + 7x - 28 = 0
We can use descartes rule of signs to find the number of positive real zeros of the polynomial.
This descarte's rule of sign states that the number of sign changes from two consecutive coefficients tell us the number of maximum number of possible positive real zeros.
In our given polynomial, there is only one sign change. Thus we conclude that there is only one possible positive real solution to the polyomial.

• three angles measuring 50°, 30°, and 100°
• three sides measuring 5 in., 12 in., and 13 in.
• three sides measuring 4 ft, 8 ft, and 14 ft
Answer:
three angles measuring 50°, 50°, 50° because they would add up to 150°. a triangles angles can only add up to 180°

Answer:
sqrt(20)
Step-by-step explanation:
The two perpendicular side lengths are equal, so using Pythagoras theorem:
