Answer:
The terms are 2, 4, and 8
Step-by-step explanation:
a+b+c=14
a^2+b^2+c^2=84
Plug in numbers.
3+6+5=14
3^2+6^2+5^2=70
This is too little, meaning the some of the terms have to be larger.
1+7+6=14
1^2+7^2+6^2=86
This is too much, meaning smaller terms are needed.
2+8+4=14
2^2+8^2+4^2=84
This is perfect.
how do i solve for this?
Step-by-step explanation:
1. KOL = 90
2.KLO = 25
3.NL= 30
4.KL = 17
workings
1.for angle
KOL =90 : the diagonals of rhombus are perpendicular to each other
2. angle LKO + angle KLO + angle KOL =180 : angles of triangle are supplementary(add to 180)
65+ KLO + 90 =180
KLO +155
KLO = 180 - 155
KLO = 25
3. NL = NO + LO: diagonals of the rhombus bisect each other
NL = 15 +15
NL = 30
4. Cos 25 = 15/KL
multiply by KL on both sides
KL × Cos 25 =15
divide by cos 25 on both sides
KL = 17
Three different sets of objects contain 2, 3, and 14 objects, respectively. How
many unique combinations can be formed by picking one object from each
set?
A. 28
B. 42
C. 84
D. 19
Answer:
C) 84
Step-by-step explanation:
Use the Fundamental Counting Principle, which states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. In this case, we have 2 ways to select one object from the first set, 3 ways to select one object from the second set, and 14 ways to select one object from the third set. So, we multiply and do 2*3*14=84
Therefore, there are 84 unique combinations

I need help with this, i did part of it but i'm desperate
Answer:
Let's add more steps.
step 6: angle AEB measures 360 - 90 -90 - 70 - 39 = 71° Reason, AECF is a quadrangonal and three of its angle measures 90, 90, and (70+39)
step 7: angles AEB and ABE are congruent: reason triangle ABE is isosceles since AE is conruent to AB
step 8 Angle BAE measures 180 -71-71 = 38°: by difference from the sum of the internal angles.
step 9: Angle BAD measures 90 - BAE = 90 - 38 = 52° Reason angles BAD and BAE are complementary.

Hope you could get an idea from here.
Doubt clarification - use comment section.
Given that:
1/(√7 - 2)
The denominator is (√7-2).
We know
The rationalising factor of (√a-b) is (√a+b)
Therefore, the rationalising factor of √7-2 is √7+2.
On rationalising the denominator them
⇛[1/(√7-2)]×[(√7+2)/(√7+2)]
⇛[1(√7+2)]/[(√7-2)(√7+2)]
Since, (a-b)(a+b) = a²-b²
Where, a = √7 and b = √2.
⇛[1(√7+2)]/[(√7)²-(2)²]
⇛[1(√7+2)]/[(√7*7)-(2*2)]
⇛[1(√7+2)]/[7-4]
⇛[1(√7+2)]/3
⇛(√7+2)/3
Hence, the denominator is rationalised.

Find the length of the hypotenuse, side c, of a right triangle with legs of length a = 6 and b = 12.
Step-by-step explanation:
6²+12²
36 + 144 is 180
c=√180
The length of the hypotenuse is the square root of 180.
What is a length?Length is defined as the measurement or extent of something from end to end.
Consider a right-angled triangle of two leg sides (a and b), and c is the third side (hypotenuse).
Given that a = 6 and b = 12,
The Pythagorean theorem states that
c^2 = a^2 + b^2
i.e. c^2 = 36 + 144
c^2 =180
Hence, the length of hypotenuse is square root of 180.

Graph the equation 2x - y = -3
PLEASE HELP, I HAVE NO IDEA HOW.
Step-by-step explanation:
Lets assume that x=0
Therefore- 2×0-y= -3
0 - y =-3
Therefore y = -3
Then lets take now the before equation
2x - 3= -3
2x = -3+3
2x=0
x=0÷2
∴ x= 0
Answer is- 0,-3
See image
You have to change the equation so it's in the form y=mx+b.
b is the y-intercept and it is a good starting point and m is the slope and it tells you directions to the next point (also how steep or flat and if it's going up or down) See image

Solve x + 5x – 14 = 0
Hey there!
Solve the equation:
Answer :x = 7/3 ✅
Explanations:x + 5x - 14 = 0
>> Add 14 to both sides :
x + 5x - 14 + 14 = 0 + 14
x + 5x = 14
6x = 14
>> Divide each side by 6 :
6x / 6 = 14 / 6
x = 14/6
Simplify the result :
14 / 6 = 2*7 / 2*3 = 7/3
Therefore, your answer is 7/3 .

1. A store in Grand Rapids, Michigan, advertised a side-by-side
refrigerator for $1,699.99.
a. What is the sales tax if the combined state and city rate is 6%?
b. What is the total purchase price?
The store Grand Rapids in Michigan placed and advert for a refrigerator for $1,699.99, also the tax rate is 6%.
Total cost = Tax + cost of refrigerator
$2719.984
Solution
let us find 6% of $1,699.99, this will be the amount paid as tax
Tax = 6/100*$1,699.99
Tax = 0.6*1,699.99
Tax = $1019.994
Now let us find the total amount paid for the refrigerator
This will be the cost of the refrigerator plus the Tax paid
Total = 1,699.99+1019.994
Total = $2719.984
