When x is equal to -5, the value of the expression 5x^2 - 2x + 5 is 140, by substitution method.
To assess an articulation for a given worth of a variable, we can substitute the worth into the articulation and improve on it. For this situation, we are given the articulation 5x^2 - 2x + 5 and we are told to assess it when x is equivalent to - 5. To do this, we substitute - 5 for x in the articulation to get 5(- 5)^2 - 2(- 5) + 5. We then, at that point, improve on this articulation by first assessing - 5 squared, which is 25. We then increase 5 by 25 to get 125, and add 10 and 5 to find the last solution of 140. In this manner, when x is equivalent to - 5, the worth of the articulation 5x^2 - 2x + 5 is 140.

Answer: 140
Step-by-step explanation:
given value
x= -5
we need to solve this equation by putting that value of
x =-5 in equation , 5x²- 2x + 5
now , 5 (-5)² - 2(-5) +5
125 + 10 + 5
= 140

Answer: "B. -5"
Step-by-step explanation:
STEP 1: Plug -5 into the equation where "X" currently is; 10 (-5) - 5 = -55
STEP 2: Multiply 10 (-5) [-50].
STEP 3: Update the equation to reflect Step 2; -50 - 5 = -55
STEP 4: Subtract 5 from -50 [-55].
STEP 5: Update the equation to reflect Step 4; -55 = -55
It is true that -55 = -55, so, therefore, the answer is "B. -5."

17, 17, 18, 19, 22, 23, 25, 27, 32, 38
If another age of 33 is added to the data, how would the mean be impacted?
The mean would increase in value to about 24.6.
The mean would increase in value to about 27.1.
The mean would stay the same value of about 22.5.
The mean would stay the same value of about 23.8.
Step-by-step explanation:
the mean would increase to about 24.6 is the answer
if u add all the ages together including the extra 33 you get 271. if u divided this by 11 you get 24.636...

The perimetre of a rectangle is 38cm length is 12.5, What is the Area?...
Answer:
A=81.25cm,B=6.5cm
Step-by-step explanation:
P=38cm
L=12.5cm
B=?
P=2(L+B)
P=2L+2B
38=2(12.5)+2B
38=25+2B
C.L.T
2B=38-25
2B=13
divide both sides by 2
B=6.5cm
therefore
A=?
L=12.5cm
B=6.5cm
so,
A=12.5cm×6.5cm
A=12.5×6.5 ×cm×cm
A=81.25×cm²
A=81.25cm²

The average of 5 numbers is 23. If the 4 numbers are 18, 27,22 and 20 then find the 5th number?
Answer:
5th number = 28
Step-by-step explanation:
23*5 = 115
The sum of the 5 numbers is
115
Then:
18 + 27 + 22 + 20 + a = 115
a = 5ft number
87 + a = 115
a = 115 - 87
a = 28
Check:
(18+27+22+20+28)/5 = 23
115/5 = 23
Answer: The fifth number is 28
Step-by-step explanation:
All numbers = 18, 27, 22, 20, x
5th number is x
So, [tex]\frac{18+27+22+20+x}{5}[/tex] = 23 (as the there are 5 numbers)
=> [tex]\frac{87+x}{5}[/tex] = 23
=> 87+x = 115
=> x = 28
Therefore the 5th number is 28

no problems

A bullet train covers 895.65km in 5 hours. What distance will it cover in an hour?
Answer:
179.13km/1hr (or 179.13 km)
Step-by-step explanation:
Distance is speed/time.
Using that, we can input
895.65 KM / 5 H
To convert 5 hours to one hour to find the speed, we need to divide both 5 and 895.65 by 5:
179.13km/1hr
which is your answer :)
Step-by-step explanation:
5 hours = 895.65km
Let 1hrs = x
:895.65/5 = x
=179.13= x
so, therefore 1hours bullet train covers 179.13km
hope that is clear to you

How can the area of this triangle be determined by forming a rectangle?
Select from the drop-down menus to correctly complete the statements.
Copy and rotate the triangle and place it next to the existing triangle to form a rectangle. The length of the rectangle is
Choose...
units. The width of the rectangle is
Choose...
units. The area of the rectangle is
Choose...
square units.
The area of the triangle is half the area of the rectangle, so the area of the triangle is
Choose...
square units.
Answer:
Length of the rectangle = 5 units
Width of rectangle = 4 units
Area of rectangle = 20 units
Area of triangle = 10 units
Step-by-step explanation:
Since I don't know the answer choices, I am assuming the base of the triangle as the length and the height as the width. Check your answer choices and switch 4 and 5 if it is the other way around
Using the graph
The rectangle formed by rotating the triangle and placing it along the original rectangle will have a length(base)
= length of the base of the triangle
= 5 units
The width of the rectangle will be the same as the height of the rectangle = 4 units
The area = length x width = 5 x 4 = 20 units
Area of triangle = half area of rectangle = 20/2 = 10 units

20:60
12:36
2:6
there r other ways you can do it tho :)
Answer: 20:60, 12:36, 2:6.
Step-by-step explanation: 4:12 = 1:3. The ratio 4:12 is equal to 1:3. which means that the second number (sn) is 3 times the first number (fn). sn = 3 * fn. The first equation: sn = 3 * 20. 3 * 20 is 60, so the second number would be 60. The second equation: 36 = 3 * fn. Divide each side by three, so the equation reads 12 = fn. The last equation: 6 = 3 * fn. Divide each side by three, so the equation reads 2 = fn.
