Answer:
The final answers are x = 1 OR x = -3.
Step-by-step explanation:
Given the equation is x^2 -3 = -2x
Rewriting it in quadratic form as:- x^2 +2x -3 = 0.
a = 1, b = 2, c = -3.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( -2 ± √(4 -4*1*-3) ) / (2*1)
x = ( -2 ± √(4 +12) ) / (2)
x = ( -2 ± √(16) ) / (2)
x = ( -2 ± 4 ) / (2)
x = (-2+4) / (2) OR x = (-2-4) / (2)
x = 2/2 OR x = -6/2
x = 1 OR x = -3
Hence, final answers are x = 1 OR x = -3.
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 's mutiplied together:
And then each exponent of 2 inside means you have two 's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
Answer:
<em>Yes, because even though their side lengths are different, their internal angles are the same.</em>

Answer:
1/8
Step-by-step explanation:
If there are 4 sections then each section is 1/4. You need to find 1/2 of one section so you will need to multiply 1/2 times 1/4 which equals 0.125 or 1/8.
