X times 4. x + x + x+ x. x would be the length of each side
Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
Answer:
x = 1
Step-by-step explanation:
Given
5x - (4x - 1) = 2 ← distribute the parenthesis by - 1
5x - 4x + 1 = 2
x + 1 = 2 ( subtract 1 from both sides )
x = 1
