Answer:
length and width of the photo are: w = 6cm l = 8cm
Step-by-step explanation:
Area = 168cm^2
Area = w • l
168 = (x + 3 + 3) • (x + 2 + 3 + 3)
168 = (x + 6) • (x + 8)
expand
168 = x^2 + 14x + 48
subtract 168 from both sides
0 = x^2 + 14x - 120
simplify
0 = (x - 6) • (x + 20)
x = 6 or -20
since we are dealing with a measurement of a physical object x > 0
x = 6cm
w = x = 6cm
l = x+2 = 8cm
Answer:
im not sure but i think the answer is 6y+(3x)

Answer:
Step-by-step explanation:
To find side x , since it the shortest side. Divide the second longest side by sqr root of 3.
Why?
This is a 30-60-90 triangle so that means the second longest side will be sqr root of 3 times more than the shortest side
RATIONALIZE the denominator
Sqr root of 6 over 3 is the answer.
This section is extra If you want to.
Since the longest side is twice the shortest side, the longest side is
Let proof
using pythagorean theorem,
So it is right.
