X + y = 8
x - y = 12
--------------add
2x = 20
x = 20/2
x = 10
x + y = 8
10 + y = 8
y = 8 - 10
y = -2
ur numbers are 10 and -2
Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
Tip: If you’re not sure on answers for I-Ready, just turn off your WiFi, pick the answer you think is right and yeah!
