The expression for the calculation the difference of the products 5 and 2 and 5 and 1 is (5 x 2) - (5 x 1).
Addition (Finding the Sum; '+') Subtraction (Finding the difference; '-') Multiplication (Finding the product; '×' ) Division (Finding the quotient; '÷')
The first thing you should be aware of is that the result of multiplying two integers is the product.
The two sets of numbers must therefore be multiplied before being subtracted.
The Expression will be:
(5 x 2) - (5 x 1)
First, work on the brackets separately
(5 x 2) = 10
(5 x 1)= 5
So, (5 x 2) - (5 x 1)
= 10 - 5
=5

Answer: 5
Step-by-step explanation: The first piece of information that you need to know is that the product is the answer when two numbers are multiplied. Therefore, you need to multiply the two sets of numbers, and then subtract.
The formula will be:
(5 x 2) - (5 x 1)=
First, do what is inside the parentheses:
10 - 5=
And solve...
5
3.14*9*9*14=3,560.76
3,560.76/3=1,186.92 (3,052.1)
3.14*9*9*4=9,156.24
9,156.24 /3=3,052.08(3,052.1)
3,052.1+3,052.1=6104.2
but i'm not sure
b. If the length of AB=3x–21, DC=34, BC=4y+32, and AD=62, find the values of x and y.
c. Find the perimeter and area of rectangle ABCD.
Answer:
Step-by-step explanation:
a) no angles are described or shown
__
b) Opposite sides are the same length, so we have ...
3x -21 = 34
3x = 55 . . . . . . . add 21
x = 55/3 = 18 1/3 . . . . . divide by 3
and
4y +32 = 62
4y = 30 . . . . . . . . subtract 32
y = 15/2 = 7 1/2 . . . . divide by 4
__
c) The perimeter is the sum of the side lengths, so is ...
P = 2(L+W) = 2(62 +34) = 192 . . . units
The area is the product of adjacent side lengths, so is ...
A = LW = 62·34 = 2108 . . . square units
