The total perimeter is 3x +21= ? first we isolate the variable by subtracting 21 on both sides. we then get 3x=21 now we divide by three on both sides and we find that x=7 to check this plug this in to x+9 x+10 and x +2 and see if x+10 is the hypotenuse.
Answer:
x=-7 x=4
Step-by-step explanation:
(x −2)(x + 5) = 18
Foil
x^2 +5x-2x-10 = 18
Combine like terms
x^2 +3x -10 =18
Subtract 18 from each side
x^2 +3x -28 = 0
Factor
What two numbers multiply to -28 and add to 3: 7 and -4
(x+7) (x-4) =0
Using the zero product property
x+7=0 x-4 =0
x=-7 x=4
Answer:
the correct answer is A , D
Answer:
10x - 1
Step-by-step explanation:
30x^2 − 33x + 3 =
= 3(10x^2 - 11x + 1)
= 3(10x - 1)(x - 1)
Answer: 10x - 1
43.54, 125.44, 54
those are the answers for the question :)
