Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation
Solution:
4 (x-3)=16
4x - 12 = 16
4x = 16 + 12
4x = 28
x = 7
4x - 3 = 16
4x = 16 + 3
4x = 19
x = 19/4
x = 4.75
Answer:
its n II m
Step-by-step explanation:
Its one of the things I remember from geometry XD
<span>Expression- arithmetic or algebraic expression (ex, 12, 5 + 3x)
Terms- number of independent items in an expression
Coefficient- number or constant multiplied by a variable (ex. 3x....3 is coefficient)
Equivalent expression- two or more expressions with the same numerical value</span>
Answer:
? = 8a
The other blank textbox = 35
Step-by-step explanation:
You are using the distributive property which means multiplying the number in front of the parentheses to the equation within the parentheses.
The number in-front is '8' for this equation.
The equation within the parentheses is ( a + 5 )
8 ( a + 5 )
You multiply the 8 to the equation in the parentheses.
8 * a
8 * 5
8 * a = 8a
8 * 5 = 40
So,
? = 8
The other blank equals 40
