Answer:
x = 
Step-by-step explanation:
(x + 6 )^2 = 49
get rid of the square , by square rooting the 49
x + 6 = 
x =
-6
x = 
means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1
therefore the answer is = or - 1
hence in terms of roots .. answer is :

5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
Answer:
68
Step-by-step explanation:
1) Find the interior angle using relations of angles in straight line I.e ( sum of angles in a straight line is 180 ) and we know the sum of all the interior angle of quadrilateral is 360 degree .
2) Solve further for x.
D.The puppy gains approximately 0.25 pound each week.
<u>x = no. of weeks</u> in f(x) = 0.25x + 1.2
