Answer:
(x-5)*(x+5)
Step-by-step explanation:
= x^2 + 5x - 25 - 5x
= x^2 +5x - 5x -25
because +5x - 5x = 0 so
= x^2 + 0 - 25
= x^2 - 25
25 can be written as 5^2
= x^2 - 5^2
we know that a^2 - b^2 = (a-b) * (a+b)
so x^2 - 5^2
= (x-5) * (x+5)

Answer: Ayden has 11 football cards,44 baseball cards and 51 Pokemon cards which totals 106 cards all together
Step-by-step explanation:
STEP 1 :
Let x represent number of football cards
He has four times as many baseball cards as football cards, let baseball cards be = 4x
Pokémon cards contain 7 more cards than his baseball collection,let Poke mon cards = 4x +7
Step 2 :
Putting in equation we have that
Football cards + Baseball cards + Pokemon cards = 106 cards
Therefore,
x + 4x + 4x+7 = 106
9x + 7 = 106
9x = 106-7
9x = 99
x =99/9 = 11
therefore football cards , x = 11 football cards
baseball cards = 4x = 4 x 11 = 44 baseball cards
Pokemon cards = 4x+7= 4x11 +7 = 44 +7 =51 Pokemon cards
Answer:
B) θ = 17.1 degrees
Step-by-step explanation:
Here we have to use the tan ratio to find the answer.
tan = Opposite / Adjacent
Given: Opposite = 4, Adjacent = 13
tan θ = 4/13
θ = tan^-1 (4/13)
θ = 17.1 degrees
Answer: B) 17.1 degrees
Thank you.
Answer:
D. 12n-5
Step-by-step explanation:
