[tex]\large\underline{\underline{ \sf\maltese Correct \ Question :- }}[/tex]
If m ∆ n means m²-2mm+n², determine the value of 3∆2.
[tex]\large\underline{\underline{ \sf\maltese Answer :- }}[/tex]
Here we are given that m ∆ n means m² -2mn +n². And we need to find the value of 3∆2 . So let's find out what does the " ∆ " operator does.
Here we can see that m² - 2mn - n² is the whole square of ( m - n)² . A inference can be taken out that the operator " ∆ " first subtracts the two numbers and then squares the obtained value to get the result . That is ,
[tex]\sf\implies m \Delta n = ( m - n )^2 [/tex]
Now similarly let's simplify out 3 ∆ 2.
Step 1 : Subtract the two numbers :-
This means we need to subtract 2 from 3 . This will give result as ,
[tex]\sf\implies Result_1 = 3 - 2 =\pink{1} [/tex]
Step 2 : Square the obtained value :-
Here , the value obtained from step 1 is 1 and the square of 1 is 1 . So our final result would be,
[tex]\sf\implies Result_{(final)}= 1^2 = \boxed{\pink{ 1 }} [/tex]

A person invests 8000 dollars in a bank. The bank pays 5% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14100 dollars?
Answer:
3 years
Step-by-step explanation:
To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.
TimeUsing this formula
A=P(1+r/n)^nt
Let plug in the formula
14,100=8000(1+0.05)^t
(1+0.05)^t=14,100/8000
(1+0.05)^t=1.7625
1.05^t=1.7625
t=log(1.7625)/log(21/20)
t=0.246/0.021189
t=11.6
Therefore how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.

8/3 = 3 (c + 5/3) how to solve step by step
Answer:
Step-by-step explanation:
8/3=3(c+5/3)
multiply both sides by 3
8=9(c+5/3)
divide both sides by 9
8/9=c+5/3
subtract 5/3 from both sides
c=8/9-5/3

Which expression is equivalen to 14.8 - 4b - [17.1 - 3b]
Answer:
-[b + 2.3]
or
-b - 2.3
Step-by-step explanation:
I'm assuming this is a multiple choice question but since you didn't list the choices I will just simplify the equation and hope for the best.
The negatives sign in front of the brackets is multiplying that quantity by -1, so first we distribute the negative to everything in the brackets.
14.8 - 4b - 17.1 + 3b
Combine like-terms
-b - 2.3

[Help Asap, Will Mark Brainliest] Answer is in the image,
Answer:
x = 1.5 and z = 118
Step-by-step explanation:
z = 118° (Opposite side angles)
Total angle of the "x" = 360°
=> 118 + 118 + (8x + 50) + (8x + 50)
=> 236 + 16x +100 ° = 360°
=> 336° + 16x = 360°
=> 16x = 360 - 336
=> 16x = 24°
=> x = 24/16
=> x = 1.5

What is the area of the trapezoid shown below?
units2
Answer and Step-by-step explanation:
Use the Pythagorean Theorem to solve for the height.
[tex]a^{2}+ b^{2}= c^{2} \\\\\\4^{2} + b^{2} = 5^{2}\\\\\\16 + b^{2} = 25\\\\\\b^{2} = 9\\\\\\b = 3[/tex]
The height of the triangle is 3.
Now we can solve the shapes in the trapezoid.
4 times 3 = 12 (Rectangle)
[tex]\frac{4 * 3}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6 (Triangle)
12 + 6 = 18 (Trapezoid)

∘
. Find \text{m}\angle X.m∠X.
Answer:
m<X = 27 degrees
Step-by-step explanation:
From △VWX, since WX = XV, this mean that the triangle is isosceles
The base angle of an isosceles triangle are equal hence <W = <X
Since <W = 27 degrees, hence m<X = 27 degrees
