Why is it not possible to form a right triangle with the lengths 2, 4 and 7? A. Because 4² – 2² ≠ 7²
B. Because 2 + 4 ≠ 7
C. Because 2² + 4² ≠ 7²
D. Because 2² + 7² ≠ 4²

Pythagorean Theorem

a^2 + b^2 = c^2

2^2 + 4^2 = 7^2?

This is not true, so the answer is C. Because 2² + 4² ≠ 7².

Let me know if this helps!

Step-by-step explanation:

answer is

B. because 2 + 4 = 7

please mark as brilliant

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
