Answer:
Step-by-step explanation:
<u>The gray triangles have</u>
- Base of 20 cm and added height of 60 cm for 2 triangles in each section of AMND and MNCB
<u>The grey area in total is</u>
- 1/2*20*60 + 1/2*20*60 = 20*60 = 1200 cm²
The correct answer is letter A
The roots are 1 +√7 and 1 -√7.
<h3>What is Quadratic equation?</h3>
A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0
Given equation:
y= x²+2x-6
First,
Half the coefficient of x and add and subtract the square of (b/2)
y= x²+2x-6+(1)²-(1)²
y= x²+2x+(1)² -6 -(1)²
y= (x+1)² -7
Now, equate y=0
(x+1)² -7 =0
(x+1)² = 7
x+1= ±√7
x=1 ±√7
Hence, the roots are 1 +√7 and 1 -√7.
