Answer:
4).16.3 infinity (unless rounded which is 16.3) for x value
5). *draw the right triangle* and label the base as 12ft and the height as 6ft
6).
A).x<4
B).x≥5
Explanation:
4).
55-6=49
49/3=16.3 infinity
5).
I multiplied the area of the triangle by two to make a square
I divided the area by 4
Which means each side would be 18
we divide this value in half to make it the area of the triangle
This means each side (base and height) are 9
Since the base is twice the size as the height, we divide the sides (18) by 3
We get the result of 6 and with this we multiply the 6 by 2 for the base
meaning 12ft is the base and 6ft is the height
Just to double check: 1/2(12)6=36ft (this is correct)
6).
A). 2x+7<11
-7 -7
2x<4
/2 /2
x<4
B).
8+2x≥18
-8 -8
2x≥10
/2 /2
x≥5
