Area= height x length
= (3x+5)²
= 9x²+30x+25
Perimeter= All sides added together
= 4 (3x+5)
= 12x + 20
Hope this helps!
Answer:
32 60 68
Step-by-step explanation:
These set of numbers are pythagorean triplets
using the formula a2+b2 =c2 with these numbers would give you an accurate relationship in a right angled triangle
Answer:37/6 gallons
Step-by-step explanation:
The answer is
A) 3:1
because the ratio is equal to the ratio of the perimeter
Subsitution
solve for y in first equation
add 2x to both sides
y=2x+8
sub 2x+8 for y in second equation
16+4x=2(2x+8)
divide both sides by 2
8+2x=2x+8
true
there are infinite solutions for x
therefor infinite soltions for y
there are an infinite number of solutions
