Answer:
55 + [tex]14\sqrt{6}[/tex]
Step-by-step explanation:
You can FOIL
[tex](7 + \sqrt{6} )^{2}[/tex] = [tex]49 + 7\sqrt{6} + 7\sqrt{6} + \sqrt{6} ^{2}[/tex]
= [tex]49 + 14\sqrt{6} + \sqrt{6} ^{2}[/tex]
= 49 + [tex]14\sqrt{6}[/tex] + 6
= 55 + [tex]14\sqrt{6}[/tex]

A grocer wants to sell fiuit in boxes.
He wants to make the boxes from square card 36 inches long and 36 inches wide as shown.
Answers
Answer:
Solution given:
For finished box
length[L]=36-4-4=28in
breadth [b]=36-4-4=28in
height[h]=4in
Now
volume of square box=l×b×h=28*28*4=3136in³
1.
the volume of finished box is 3136in³
2.
if we change the 4 inches into different measurement ,its maximum or largest volume is 3136in³.
As volume is constant.
The volume of the box will be 3136 cu. unit and the largest volume the box can be made of is also the same.
What is volume ?The amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters)
The given square after getting folded turns into a box of 28*28*4 inches
The volume of the box can be detrmined by using the formula of volume of the cuboid.
Volume of the cuboid = 28*28*4
=3136 cu.inches
The largest volume that the box can have is 3136 as when increasing the height the length or the width will decrease and so does the volume.

The distance between D(-3,5) and E(x, 9) is 15. Find the value(s) of the
missing coordinate.
Answers
9514 1404 393
Answer:
x ≈ -17.457 or 11.457
Step-by-step explanation:
The distance formula can help.
d = √((x2 -x1)² +(y2 -y1)²)
Substituting given values, we have ...
15 = √((x -(-3))² +(9 -5)²)
225 = (x +3)² +16 . . . . . . . . square both sides
209 = (x +3)² . . . . . . . . . . . subtract 16
±√209 = x +3 . . . . . . . . . take the square root
-3 ± √209 = x . . . . . . . . subtract 3
x ≈ -17.457 or 11.457

HOW TO DO THIS QUESTION
Answers
Answer:
see explanation
Step-by-step explanation:
The dot above the 5 indicates the 5 is repeating , that is
2.7555...
We require 2 equations with the repeating 5 placed after the decimal point.
let x = 2.7555,,, ( multiply both sides by 10 and 100 )
10x = 27.55... → (1)
100x = 275.55... → (2)
Subtract (1) from (2), thus eliminating the repeating 5
90x = 248 ( divide both sides by 90 )
x = [tex]\frac{248}{90}[/tex] = [tex]\frac{124}{45}[/tex]

larger smaller a) 3 m = ________ cm
larger smaller b) 28 cm = _________mm
larger smaller c) 2.4 km = _________m
larger smaller d) 485 mm = _________cm
larger smaller e) 35 cm = ____________m
larger smaller f) 2.4 m = _____________km
larger smaller g) 2495 mm = __________m
Answers
1.
a) metres to centimetres :
multiply length by 100
b) metres to millimetres:
multiply length by 1000
c) kilograms to grams:
multiply the mass value by 1000
d) litres to millilitres :
multiply volume by 1000
2.
a) 3 m = 3× 100 = 300 cm
b) 28 cm = 28 × 10 = 280 mm
c) 2.4 km = 2.4 × 1000
= 24 × 10^-1 × 10^3
= 24 × 10^2 =2400 m
d) 485 mm =485 / 10
= 485 / 10 ^1
= 485 × 10 ^-1
= 48.5 cm
e) 35 cm = 35 / 100
= 35 /10^2
= 35 × 10 ^ -2
= 0.35 m
f) 2.4 m = 2.4 / 1000
= 24 × 10 ^-1 / 10^3
= 24 × 10^-1 × 10 ^-3
= 24 × 10 ^ -4
= 0.0024 km
g) 2495 mm = 2495 /1000
= 2495 /10^ 3
= 2495 × 10 ^-3
=2.495 m

Answers
Answer:
Mean= Summation /number of terms

=6.
Median
To do this
arrange all terms from smallest to biggest
That is
2,4,4,5,7,8,9,9
The two middle numbers are
5 and 7.
To get the median
add both and divide by 2
5+7 = 12... 12/2 =6
Median=6
Mode.... This is the number that appears most
Mode = 4 and 9.(Bimodal) Both appear equally.
Range: Highest - Lowest
= 9-2 =7.
Answer:
mean = 6 median = 6 mode 9 and 4 range = 7
Step-by-step explanation:
mean = 2+4+4+5+7+8+9+9÷ 8 = 6
median = 5+7÷2
mode = 9 and 4
range = 9-2=7
