Answer:
7(2+x)(2-x)
Step-by-step explanation:
Both terms are perfect squares,use the difference of square formulas
a^2-b^2=(a+b)(a-b) where a=2 and b=x
The correct answer is 44.4%
Answer:
19.21m is the diagonal
Step-by-step explanation:
We are looking for the diagonal, which makes it the hypotenuse of a right triangle, with the legs being 15 and 12
We can use the Pythagorean theorem
a^2 + b^2 = c^2
12^2 + 15^2 = c^2
144 +225 = c^2
369 = c^2
Take the square root of each side
sqrt(369) = sqrt(c^2)
19.209 =c
19.21 m = c
