Answer:
a=x and b=9
(x+9)(x−9)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)
Answer:
x = 15
Step-by-step explanation:
Consider the right triangle on the left with hypotenuse h₁ , then
Using Pythagoras' identity
h₁² = x² + 9²
Consider the right triangle on the right with hypotenuse h₂ , then
h₂² = x² + 25²
Now consider the large right triangle with legs h₁ and h₂ , then
h₁² + h₂² = (9 + 25)² , substitute values
x² + 9² + x² + 25² = 34² , that is
2x² + 81 + 625 = 1156
2x² + 706 = 1156 ( subtract 706 from both sides )
2x² = 450 ( divide both sides by 2 )
x² = 225 ( take the square root of both sides )
x =
= 15
A) 5 minutes, 7 balloons
He makes 36 sculptures in 180 minutes. To find the number of minutes to make 1 sculpture, divide by 36: =5. He uses 252 balloons to make 36 sculptures. To find the number of balloons in 1 sculpture, divide by 36
Answer:
y=x-2
Step-by-step explanation:
we know that y-intercept is -2
y=?x-2
So now we would have to find slope
the slope would be 1
soo that makes the equation would be
y=x-2
I hopes this helps.
Have a good day!!
