As we know that
Diagonal of square = √2 ( side of square )So , we need to find side of square first
Using area of square = Side²
➩ 144 = S²
➩ S = √144
➩ Side = 12 cm
Now ,
➨ Diagonal = √2 ( 12 )
➨ Diagonal of square = 12√2

x2 + 5x2 – 3x – 20 = 0
Answer:
6x2−3x−20
Step-by-step explanation:
Let's simplify step-by-step.
x2+5x2−3x−20
=x2+5x2+−3x+−20
Combine Like Terms:
=x2+5x2+−3x+−20
=(x2+5x2)+(−3x)+(−20)
=6x2+−3x+−20
Which choice is equivalent to the expression below?
V-12
A. -24/5
B. 2123
C. -121
D. 231
E. 12 i
Given:
Consider the expression is [tex]\sqrt{-12}[/tex].
To find:
The value of given expression.
Solution:
We have,
[tex]\sqrt{-12}[/tex]
It can be written as
[tex]\sqrt{-12}=\sqrt{-1\times 12}[/tex]
[tex]\sqrt{-12}=\sqrt{-1}\times \sqrt{12}[/tex] [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]
[tex]\sqrt{-12}=i\times \sqrt{12}[/tex] [tex][\because \sqrt{-1}=i][/tex]
[tex]\sqrt{-12}=\sqrt{12}i[/tex]
Therefore, the value of given expression is [tex]\sqrt{12}i[/tex].

Cameron needs to order some new supplies for the restaurant where he works. The
restaurant needs at least 598 spoons. There are currently 194 spoons. If each set on
sale contains 8 spoons, write and solve an inequality which can be used to determine
x, the number of sets of spoons Cameron could buy for the restaurant to have enough
spoons.
Answer:
Inequality: 8x+194_>598
Answer:x_>50.2
Step-by-step explanation:
I have delta math! I risked getting the answer wrong for this question lol. But this is correct just!
404 spoons are required for the restaurant for the fill needs.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say the number of sets required = x
Then,
8x will be the total number of spoons.
So,
8x + 194 ≥ 598
8x ≥ 404
x ≥ 50.5
A number of spoon required = 50.5 × 8 = 404 spoons.
Hence "404 spoons are required for the restaurant for the fill needs".

The proportional relationship between the number of inches a candle has burned away, b, at any time in hours, t, can be represented by the equation b = 0.25tb=0.25t. What is the constant of proportionality from the time in hours to the inches of candle that has burned away?
Answer:
k = 0.25t^2
Step-by-step explanation:
Given the equation :
b = 0.25t
b = number of inches that has burned away
t = time
From our knowledge of variation;
Since candle length will decrease with time ;
b α 1/ t
b = k/t
Where k is the proportionality constant
Comparing the equation :
b = 0.25t
k/t = 0.25t
k = 0.25t^2

Answer:
6/76 to 7 (some authors would write this "6 is to 7")Step-by-step explanation:
The commonly used symbols for ratios are a colon or a fraction bar. Words can also be used.
6 : 7 = 6/7 = 6 to 7
__
When the ratio is part of a proportion, then it might be written ...
6 is to 7
as in ...
6 : 7 :: 12 : 14 . . . . . . . 6 is to 7 as 12 is to 14
Which statement best represents the equation below 10+(-10) =0
Answer:
im not sure if this is the answer you wanted hope it helped though
Step-by-step explanation:
Applying the BODMAS rule where B=Brackets ,O=of,D=Division,M=multiplication,
A=Addition,S =subtraction
For any equation in which multiple operation is to be done its depends on the preference of the operation to be performed.
The preference followed is BODMAS
In the above question first multiplication will be performed first and then the addition is performed.
10+10*0+10
10+0+10
Answer is 20
Answer:
D. a car goes 7 feet and then reversed 7 feet.
Step-by-step explanation:
The statement above can be set up in a simple equation.
7 - 7 = 0
This can best represent the equation 10 + (-10) = 0, because they both end up with the same result.
10 + (-10) = 10 - 10 = 0

what is 9.4 rounded to the nearest tenth?
Answer: the answer is going to be 9
Answer:
9.4 rounded to the nearest 10th - 9
Step-by-step explanation:
If the tenth in the decimal is 4 or lower, (like 9.4 or 9.3) It would round down to 9, but if it were 5 or higher like (9.5) it would be 10.00 or 10 :)

Answer:
<C =10°
Step-by-step explanation:
The sum of angles in a triangle is 180°. Hence,
<C+<D+<E =180
Given
<C =x-4
<D = 11x-11
<E = x+13
Substitute
x-4+11x-11+x+13 = 180
13x-2 = 180
13x =180+2
13x = 182
x = 182/13
x = 14
Get <C
Since <C = x-4
<C = 14-4
<C =10°
Answer: <C =10°

Answer:
A. Juan wins the race
B. At about 7 minutes J(t )= A(t)
C. 2 minutes
Step-by-step explanation:
A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio
B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.
C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes
