Answer: x = +4 or -4
Step-by-step explanation:
x² - 1 = 15
x² = 15 + 1
x² = 16
Therefore, to solve for x we take the square root of both side
√x² = +/-√16
x² = +/-4
so, x = +4 or -4
Term 11=a+10d
Here
a=10
d= 7-10= -3
Term 11;
=10+(10×-3)
=10+(-30)
= -20 is the answer
Thank you Hope it helps dear
The solution to the given equation is x > 5.3
<h3>Solving linear inequality</h3>
Inequality are expression that are separated by an equal sign.
Given the inequality;
16(1/4 x - 1/2) > 24- 2x
Expand
4x - 8 > 24 -2x
Collect like terms
4x + 2x > 24 + 8
6x > 32
x > 32/6
x > 5.3
Hence the solution to the given equation is x > 5.3
