This is easy just find out what 5^2 equals which will be 5x5=25 (when dealing with a squared number you will always times it by itself. so if you had 10^2 it would be 100.) so now that we know 5^2 is 25 we then can add the 20 which gets 25+20=45! Hope this helps!
Step-by-step explanation:
x+y=180
x=180-y------(i)
x-y=70------(ii)
Now,
Putting the value of x in equation (ii)
x-y=70
(180-y)-y=70
180+2y=70
2y=70-180
2y= - 110
y= - 110/2
y= - 55
Again,
x=180-(-55)
x=235
x-y=70
x-(-55)=70
x+55=70
x=70-55
x=15
area = x^2 -10x+25
side = sq root area
x^2-10x+25 = (x-5)(x-5) = (x-5)^2
=》 side = (x-5)

Answer:
2x^2 - 9x - 5
Step-by-step explanation:
This is a multiplication problem; it's not an equation and thus can't be "solved." Rather: "Multiply out (2x+1)(x-5)."
(2x+1)(x-5) = 2x^2 - 10x + x - 5, or 2x^2 - 9x - 5. This is the "product" of (2x+1)(x-5).
