Answer:
sum of exterior angles of polygon = 360°
therefore,
z = 360 - (105+145)
z = 360 - 250
z = 110°
Answer:
126 sq. meters
Step-by-step explanation:
A = lw
= 9(14)
= 126 sq. meter
If denomenators are same, we can add
remember
(a/b)+(c/b)=(a+c)/b
so
(3y/2)+(9/2)=(3y+9)/2
Answer:
1.69
Step-by-step explanation:
(0.3)²+2(0.3)+1
We can substitute<span> y in the second equation with the first equation since y = y. The solution of the linear system is (1, 6). You can use the </span>substitution<span> method even if both equations of the linear system are in standard form</span>
