Greetings!
"<span>The difference of six times a number and 7 is -49"...
In number and variables, this would be:
</span>
<span>
Add
7 to both sides.
</span>
<span>Simplify.
</span>
Divide both sides by
6.
Simplify.
Hope this helps.

Answer:
(-∞, 0) U (8, ∞)
Step-by-step explanation:
<h2>28 units²</h2><h2>____________________</h2>
<u>Step-by-step explanation:</u>
length = 8 units
breadth = 3.5 units
area = length × breadth
= 8 × 3.5
= 28 units²

The formula for the radius r in terms of x . and for the maximum areas is x=2/+4
Given that,
y forms a circle of radius r
y=2r
r=y/2
(2-y)- forms Square Side x
(2-y) = 4x
x=(2-y)/4
Now Sum of Area's=Area of Square +Area of Circle
Sum = r² + x²
Substitute the r and x values in above equation,
A(y)= y²/4+(y-2)²/ 16
To maximize Area A(y)
A'(y)= 0
2y/4 + 2(y-2)/16 =0
y/2 + (y-2)/8 =0
y = 2/+4
Y max will be max, x to be maximum.
for maximum sum of areas,
x=2/+4
Hence,The formula for the radius r in terms of x . and for the maximum areas is x=2/+4
