Since both terms are perfect squares, factor using the difference of squares formula,
a² − b² = (a + b) (a − b) where a = 5(x + 5/4) and b = 4 (x (7/4) ).
− (12x + 25/4) (2x + −25/4)
Answer:
63
Step-by-step explanation:
64+53+ (ㅣ) = 180
117 + (ㅣ) = 180
(ㅣ) = 63
Answer:
the answer is 1350
Step-by-step explanation:
add 450 together three times or multiply by 3
450 x 3 = 1350
Substitue y=3x into the other equation to get 3x=-x+4. Solve this to get 4x=4 therefore x=1.
knowing this, y=3
Use the equation a^2 + b^2 = c^2.
225 + 1296 = c^2
1596 = c^2
Square root both
39 = c
