To solve this you first expand the brackets.
4x^2 - 20x + 25 = 49
Then make it equal 0.
4x^2 - 20x - 24 = 0
Now solve the quardratic.
x^2 - 5x - 6 = 0
(x - 6)(x + 1) = 0
x = 6 or x = -1
Answer:
0.55
Step-by-step explanation:
0.25-0.1=0.15
0.7-0.4=0.3
0.4+0.15=0.55
0.55+1.5=0.7
Answer:
x =2
Step-by-step explanation:
The x- intercept is when y = 0
Hence, 5x - 2y = 10
5x - 2(0) = 10
5x = 10
Therefore, x = 2
The correct answer is B. You know this because you are just adding like terms or in this case the same exponents.
Answer:
B : 5/6
Step-by-step explanation:
By doing some simple fraction, this would be the only thing that'd be correct!
