Answer:
x₁ = -4
x₂ = 3
Step-by-step explanation:
x²+ x + 12 = 0
x = {-1±√((1²)-(4*1*-12))} / (2*1)
x = {-1±√(1+48)} / 2
x = {-1±√49} / 2
x = {-1±7} / 2
x₁ = {-1-7} / 2 = -8/2 = -4
x₂ = {-1+7} / 2 = 6/2 = 3
Check:
x₁
-4² + (-4) - 12 = 0
16 - 4 - 12 = 0
x₂
3² + 3 - 12 = 0
9 + 3 - 12 = 0
Answer:
when there are no parentheses around the base, this being -2 we put parentheses around the the 2 and the exponent so it will look like -(2^6) making whatever answer you get negative.
when you put parentheses around the base (-2)^6 you will get 64

Step-by-step explanation:
The area of the polygon is 470596 units²
<h3>What is Area of Regular polygon?</h3>
The region occupied by it in a two-dimensional plane. The areas or formulas for areas of different types of polygon depends on their shapes.
Given that: side are 7 cm,14 cm,14 cm,7 cm,7 cm,7 cm
Area of Polygon= 7*14*14*7*7*7
= 343*195*7
= 470596 units²
The area of polygon is 470596 units²
