Answer 1
Answer: Same signs = positive answer
Different signs = depends on the largest number
Answer 2
Answer: Example:  -2 times -2= 4  -2times 2= -4 

So basically when you divide and multiply the same signs . the answer is positive. if the signs are different then the answer is negative

How do I solve 3a=57

Answers

Divide 3 from both sides to get a=57/3 then a=19
You have to do the reverse operation to 57 so you have to do 57÷3 which is 19

Ok so,
#1 is a triangular pyramid as we can see.
The surface area formula of a pyramid is:
S.A = Area of base + (1)/(2) × perimeter of base × slant height
The base is 8 cm ( 4cm + 4cm = 8cm)
Height of the triangle is 3.5 cm
Area formula of a triangle is:
A = (1)/(2)bh
P = all sides added together

Substitute them:
S.A = (1)/(2) × 8 × 3.5 + (1)/(2) ×(8 + 8 + 8) × 5
S.A = 14 + 60
       = 74 cm²

and #2 is a squared-based pyramid
Same formula applies.
And we know that the area formula of a square is:
A = s²
P = add all sides together

S.A = 2² + (1)/(2) × (2 + 2 + 2 + 2) × 3
       = 4 + 12
       = 16 ft²

Chris is making a table-top from some leftover tiles he has 9 tiles that measures 3 1/8 inches long and 2 3/4 inches wide what is the area he can cover with these tiles

Answers

The product is 8.59375 or 8 19/32.

77 ¹¹/₃₂ in²

The area that he can cover with these tiles is 77 ¹¹/₃₂ in²

Further explanation

To solve the above questions, we need to

recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Number of Tiles = N = 9 tiles

Length of Tiles = L = 3¹/₈ inches

WIdth of Tiles = W = 2³/₄ inches

Unknown:

Total Area = A = ?

Solution:

Area of One Tile.

Area of Rectangle=Length×WidthArea of Rectangle=Length×Width

Area of Rectangle=318×234Area of Rectangle=381×243

Area of Rectangle=81932 in2Area of Rectangle=83219 in2

Total Area.

Total Area=Number of Tiles×Area of One TileTotal Area=Number of Tiles×Area of One Tile

Total Area=9×81932Total Area=9×83219

Total Area=771132 in2Total Area=773211 in2
