-2a+4 because you have to distribute
Answer:
<h3> -5n = 1 ⇒
n = -¹/₅</h3><h3> n+15 = (-10) ⇒ n = 25</h3><h3> n/5 = -1/5 ⇒ n = -1</h3><h3> n-13= -12 ⇒ n = 1</h3>
Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
Hey there! :D
25% represents a quarter of a number.
If 21 is a quarter of a number, multiply it by 4.
21*4= 84
21 is 25% of 84.
I hope this helps!

It would be 9 yards
If it is a square then each side is equal so 36/4=9
Shape D is not a quadrilateral
