5b plus 5-3b-7 is 2b-2.
10a + 5b
(16 + 4x)/2 2(4 + x)
2(4x+8) 4(2x+4) 8(x+2)
Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b
It is 10b + 2c
6(b + 2)(5b - 2)
(1) 4a-5b=7 (2) 4a+5b=17 (1)-(2) gives 4a-5b-(4a+5b)=7-17 then -10b=-10 so b=1 from (2) one gets 4a=17-5b=17-5x1=12 so a=3 (3,1) is the solution
the answer is a(n) equationequationWhen two expressions are equivalent they can form an equation.
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
Two or more expressions (equations are examples) that are equal to or equivalent to each other; for example: (X+2)(X+4) = X^2+6X+8.
It is: (-5b+2)(b-1) with the help of the quadratic equation formula
Such expressions illustrate the distributive property of multiplication over addition in the field of real numbers.
They are: 6d+6 or 6(d+1)
No. 7b - 2b = 5b
2. 2 plus 2 equals 4 and 2(2)= 4
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
4(5b - 6a^2)(5b + 6a^2)
2 plus n is the true one, but 1 plus n is not?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
