Answer:
2x^2 + 2x - 83 = 0
Step-by-step explanation:
Consecutive integers differ by 1
Let the first number be x
The next will be (x+1)
The sum of the squares of these two numbers is 85
so we have;
x^2 + (x + 1)^2 =85
= x^2 + x^2 + 2x + 2 = 85
2x^2 + 2x + 2-85 = 0
2x^2 + 2x - 83 = 0
Answer:
The polygons are not similar.
Step-by-step explanation:
They do not have proportional side lengths, so they are not the same
Answer:
x=4. y= 7/2----3.5
Step-by-step explanation:
for B the answer could also he m=0, b=7/2 if you're looking for the function
if you want the alt version it could also be y=3 1/2/y=3.5
Ok I know how to do this but what do I need to do?
Plug y= x+5 in 3x+y= 25, we have:
3x+ (x+5)= 25
⇒ (3x+x)+ 5= 25 (combine like terms)
⇒ 4x= 25-5
⇒ 4x= 20
⇒ x= 20/4
⇒x= 5
y= 5+5= 10
Final answer: x=5, y=10~
