using completing the square method in quadratic equation 5x²+ 11x + 2=0
Answer:
x= 1/5 or -2
Step-by-step explanation:
5x² +11x +2= 0
(Divide through by the coefficient of x²)
5x²/5 + 11x/5 + 2/5 = 0/5
x² + 11x/5 + 2/5 = 0
(take the constant to the other side)
x² + 11x/5 = -2/5
(Add 1/2 of the coefficisint of x all square to both sides)
x² + x + (11/5 × 1/2)² = -2/5 + (11/5 × 1/2)²
x² + x + (11/10)² = -2/5 + (11/10)²
x² + x + (11/10)² = -2/5 + 121/100
(eliminate x )
x² + (11/10)² = (20(-2) + 121 ) ÷ 100
(x + 11/10 )² = (-40 + 121) ÷ 100
(x + 11/10 )² = 81/100
(square both sides)
x + 11/ 10 =√(81/100)
x + 11/10 = 9/10
x = -11/10 +or- 9/10
x = -11/10 + 9/10 or -11/10 - 9/10
x = (-11 + 9) ÷ 10 or (-11-9) ÷ 10
x = -2/ 10 or -20/10
x = -1/5 or -2

Answer:
£20 - ( 2.49 + 4.99 + 3.99)
= 20 - 11.47
= £8.53.
Step-by-step explanation:
Answer:
She will recive £ 8.53 in change.
Step-by-step explanation:
£3.99 + £2.49 + £4.99 = £11.47
^ (All the prices combined to subtract later)
£20.00 - £11.47 = £8.53

What is an algebraic expression?An Algebraic expression shows the expression of variables with numbers. The purpose of an algebraic expression is to determine the unknown variable represented by an unknown letter.
From the given information:
2(6x + 4) - 6 + 2x = 3(4x + 3) + 1
Open brackets
12x + 8 - 6 + 2x = 12x + 9 + 1
Collect like terms
12x + 2x - 12x = -8 + 6+9 + 1
14x - 12x = -8 + 16
2x = 8

What is the slope of the line?answer
Answer:
Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
Step-by-step explanation:
Answer:
The slope of the line is -2.
Step-by-step explanation:
Because the line is going down from left to right it is considered a negative slope. The rise is -2 and the run is 3, so the slope of the line in integer form is -2.
But, if it was in fraction form the slope would be -2/3.

what is the value of 2.57 1.75
Answer:
2.57 - 1.75 = 0.82
Step-by-step explanation:
Let us assume that we need to find the value of 2.57 - 1.75 i.e. we need to subtract 1.75 from 2.57. It can be done as follows :
The first number is 2.57 and other no is 1.75.
In 2.57, 2 is in ones place, 5 is in tenths place and 7 is in hundredths place.
In 1.75, 1 is in ones place, 7 is in tenths place and 5 is in hundredths place.
Subraction :
2.57
- 1.75
= 0.82
Hence, the value of 2.57 - 1.75 is 0.82

M-5=49 please answer I need help
Answer:
M=54
Step-by-step explanation:
If you are trying to find the value of M, you add 5 to both sides
M-5+5=49+5
this way the M is all by itself on the left side of the equal sign because -5+5=0
when we combine the like terms we get
M+0=54
therefore M=54
Also 54-5=49

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three point
Complete question :
Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
Answer:
0.405224
Step-by-step explanation:
Given that:
p(success) = p = 74% = 0.74
If given 3 free throws ; probability of making all 3
Using binomial fórmula :
p = 0.74 ;
1 - p = 0.26
P( x = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 3) = 3C3 * 0.74^3 * 0.26^0
P(x = 3) = 1 * 0.405224 * 1
P(x = 3) = 0.405224
Evaluate the expression.
P(8,1)

Regional erosion occurs at a rate of 2 m per 1,000 years.
How much regional erosion will occur over 1,000,000 years?
A) 20 m
B) 200 m
C) 2,000 m
D) 100,000 m
Answer:
200
Step-by-step explanation:
It's 200 because you would take the 1,000 and multiply it by the power of 3, which is 100,000. So therefore you would do the same thing with the 2, which 2 to the power of 3 is 200. There is your explanation.

In ΔKLM, m = 18 inches, ∠M=124° and ∠K=29°. Find the length of k, to the nearest 10th of an inch
Answer:
10.5
Step-by-step explanation:
sin29
k
=
sin124
18
Plug in. Opposite sides go together.
k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5
k=
sin124
18sin29
≈10.526≈10.5
The required length of k is 10.5 inches for the given triangle.
What is the sine rule?The sine rule defines the side length ratios of triangles to their opposing angles. This proportion is true for all three sides and opposing angles.
a/sinA = b/sinB = c/sinC
The triangle is given in the question, as follows:
In ΔKLM, m = 18 inches, ∠M=124° and ∠K=29°.
We have to determine the length of k.
As per the sine rule, the required solution would be as:
m/sin∠M = k/sin∠K
Substitute the known values and we get
18/sin 124° = k/sin 29°
k = (18/sin 124°) × sin 29°
k ≈ 10.5
Thus, the length of k is 10.5 inches.
