If the 2 is little and on top of the a, then it's called "nine a squared."
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
Answer:
x^2 + 14x + 49
Step-by-step explanation:
Use the distributive property:
(x + 7)(x + 7) = x^2 + 7x + 7x + 49 = x^2 + 14x + 49
$57.18 + 256.79 = 313.97
313.97 - 68.42 = 245.55
245.55 - 50.00 = 195.55
195.55 - 31.06 = 164.49
that’s your answer
Answer:
( 5x + 1 ) ( x - 4 )
Step-by-step explanation:
5x² - 19x - 4
= 5x² + x - 20x - 4
= x ( 5x + 1 ) - 4 ( 5x + 1 )
= ( 5x + 1 ) ( x - 4 )
Hence, factorized.
