162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.
Answer:
(x - 5i)(x + 5i)
Step-by-step explanation:
Write this as x^2 + 25. Solving for x^2, we get x^2 = -25.
Recall that the square root of a negative number is an imaginary one. √(-25) equals ±5i (there are two roots, one positive and one negative).
Then x = ±5i.
In factored form, the given expression is (x - 5i)(x + 5i).
Answer:
False.
Step-by-step explanation:
If they have the same slope and same intercept they will have the same line. So they will have infinite solutions.
Answer: It is letter C. 1/22
Step-by-step explanation:
Change 2 3/4 to an improper fraction to get 11/4, then multiply 1/8 by the reciprocal of 11/4 which is 4/11.
1/8 x 4/11= 4/88
4/88 simplified = 1/22
A+2.4=7.8
a=-5.4
5.4+2.4=7.8
