The first one is the correct answer due to 4 is the initial height of the plaint and 0.75 are inches that being added every week
Area of trapezoid : (Base 1 + base 2) x h x 1/2
Let's solve!
( 2+6) x 5 X1/2
= 40x1/2
=20
20 in squared is the area!
Answer:
{3-i, 3+ i}
Step-by-step explanation:
hello : the equation is : x²-6x+10 =0
because : (3+i)²-6(3+i)+10 = 9+6i+i²-18-6i+10 =9+6i-1-18-6i+10 =0...right
same method for 3-i... (all quadratic equation have two conjugate solution)
4(-8+4.5)
-32+18
-14
6.25+(-8.25)
-2
-14/-2
7
The answer is 7.
