Answer:
There's 2 solution, x= -1 and x= 2
Step-by-step explanation:
<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is
. We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression
to be the side of the square.
As the function forms the square after adding some
unit tiles, 

From comparision, 
∴ 8 more unit tiles are required to complete the square.
30+4X=90 (right angle is 90°)
X=15
4 (15)= 60
30+60= 90 so you know it's right
Answer:
2/3
Step-by-step explanation:
1/2 ÷3/4 =
1/2 ×4/3 = 4/6

Answer:
13= -14x
Step-by-step explanation:
(4×2)-(4×1x)=(5×1)-(5×2x)
8-4x=5-10x
8+5=-4x-10x
13=-14x
Hopefully this will help
