The product of a sum and a difference with 31 times 29 is:
(30+1) x (30-1)
sum to difference

a product
= 30² - 1²
= 900 - 1
= 899
The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).
It means: 1/10 times 3.7 = 0.37
Multiplicand times multiplier equals product. If the expression has a variable, the numerical factor of the variable is the coefficient.
If x is 4 then 34.5x evaluates to 34.5 times 4 = 138
four times the product of negative three and a number
The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).
It is simply: 9c which means 9 times c
It means: 1/10 times 3.7 = 0.37
Multiplicand times multiplier equals product. If the expression has a variable, the numerical factor of the variable is the coefficient.
If x is 4 then 34.5x evaluates to 34.5 times 4 = 138
It would be: 3(7-d) as an algebraic expression
Multiplicand times multiplier equals product. If the expression includes a variable, the numerical factor is the coefficient.
There is no variable in (8x12)+8, so it would be called an arithmetic expression. It would evaluate to 96+8 = 104.
four times the product of negative three and a number
2(-6n)
8(5x) = 40x
0.8 x 12 = 9.6
