A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6
We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
Answer:
(A) 360
Step-by-step explanation:
360*.40=144
Answer:
(x + 2)² = 8
Step-by-step explanation:
To complete the square, write the equation standard form.
-4 + 4x + x² = 0
x² + 4x - 4 = 0
Take the middle term 4x and divide the coefficient in 2 and square it. Here it is 4/2 = 2. 2² = 4. Add 4 to both sides.
x² + 4x + 4 - 4 = 0 + 4
(x + 2)² - 4 = 4
(x + 2)² = 8
