Answer:

W=35, L=45

Step-by-step explanation:

L= W+10

L×W=1575

(W+10)W=1575

W^2+10W=1575

W^2+10W-1575=0

(W-35)(W+45)=0

W=35 or W=-45 (cant be negative) so has to be 35

And L = W+10=45

The sum of x and 8 is less than 72​
Vanyuwa [196]

Answer:

x<84

Step-by-step explanation:

First, write an inequality. We know it is not an equation because of the words "less than". Also, x and 8 are being added because of the word "and". Here's the inequality: x+8 < 72. Now, subtract 8 on both sides so x is isolated. Our simplified inequality looks like this: x < 84.
