its the 3rd one..............................
It's D for the answer. Someone else had that question too.
2x2 +12x=32
2x2+12x-32=0 ( 2*32=64, 16*4=64.)
2x2 + 16x-4x-32=0
2x2-4x+16x-32=0
2x(x-2) +16(x-2)=0
(2x+16)(x-2)=0
x=-16/2 or x=2
{x=-8,2}
10,20,30,40
you know this because if you do prime factorization both 2 and 5 are prime numbers found in those numbers.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. The translation is as follows:
a) 4 - k
b) 8 - x
c) 6 + d
d) x + 5
e) 8 / x
f) 2 + x = 8
g) 1/2n-12
<h3>What is meant by algebraic expressions?</h3>
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
Arithmetic operations like subtraction, addition, division, multiplication, and exponentiation are used to combine variables and integers to produce any algebraic expression. A variable, a number, or a variable and number with an exponent as a product can all be used as the phrase.
The translation is as follows:
a) 4 - k
b) 8 - x
c) 6 + d
d) x + 5
e) 8 / x
f) 2 + x = 8
g) 1/2n-12
