[See Below]
Step-by-step explanation:
If you replace the x with -1 and evaluate the function you get -5.
Step-by-step explanation:
90÷0.018=5000
90÷0.18= 500
90÷1.8 = 50
90÷18 =5
90÷180 =0.5
Answer:
c.
Step-by-step explanation:
If its isoceles, then LM is equal to LN. This means 3x-2 = 2x+1. 3x minus 2x is x. 2 plus 1 is 3. So x = 3. So it needs to be c or d. since LM and LN are the same answers, go to MN and find the answer. If you siubstitute 3 for x in 5x-2, then you get 13.
Answer:
49x² + 42x + 9
Step-by-step explanation:
Given
(7x + 3)²
= (7x + 3)(7x + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis
= 49x² + 21x + 21x + 9 ← collect like terms
= 49x² + 42x + 9
