<span> First convert the linear dimensions from feet to yards: 12 ft = 4 yd, 15 ft = 5 yd. Then when you multiply yards by yards, you get an area in square yards, namely, 4 yd * 5 yd = 20 square yards.</span>

A=lxw

a=area
l=length
w=width

so a=12*15
so the area would be 160 ft.

Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

$y =x5 - 3$

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

$y =x5 - 3$

$y =8*5 - 3$

$y =40 - 3$

$y = 37$

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

$y =x5 - 3$

$42 = x5 - 3$

Collect like terms

$x5 = 42 + 3$

$x5 = 45$

Divide both sides by 5

$x = 9$

3 + x ≥ 12 solve the inequality

kherson [118]

$3 + x \geq 12 \\ \\ x \geq 12 - 3 \\ \\ x \geq 9 \\ \\$

You just subtract 3 from each side and then simplify (12 - 3) which is 9.

The final result is: x ≥ 9.
