Answer:
<u>x₁ = i√5</u>
<u>x₂ = -i√5</u>
Step-by-step explanation:
Let's solve the equation using square roots.
4X^2 + 20=0
x² + 5 = 0 (Dividing by 4 at both sides of the equation)
x² = -5 (Subtracting 5 at both sides of the equation)
√x² = √-5 (Square root to both sides of the equation, √-1 = i)
x = +/- i√5 ( (Roots of the solution)
<u>x₁ = i√5</u>
<u>x₂ = -i√5</u>
Answer:
B. 128
Step-by-step explanation:
so the sum of the interior angle is 180
180 - 76 is 104
since both sides are the same divide 104 with 2 to get 52
to find x = 180 - 52 = 128
Let’s turn the mixed number into a fraction
3/2 x 1/2
Multiply across
3/4
