Answer:
The second and fourth one is right
Step-by-step explanation:
A²+ B² = C²
15² + 20² = 25²
225 + 400 = 625
625 = 625
16² + 30² = 34²
256 + 900 = 1156
1156 = 1156

Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
