Answer:
A
Step-by-step explanation:
49y² - x² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
49y² - x²
= (7y)² - x²
= (7y - x )(7y + x) → A
From corresponding angles theorem, we can see the 2 angles are equal.
16x+13=18x-1
2x=14
x=7
Done!
Any questions just leave them in the comments and I will answer.
80 degrees because it decreases by a half each time so by the time it is E (the fourth letter) it has gotten to 20 so the answer is 160
There are 30 treasures.
80% are found:
80% of 30 = 0.8 x 30 = 24
Bella found 24 of them
30 - 24 = 6
There are 6 more left to find
Answer:y=-5/3x+1
-5/3
1
Step-by-step explanation:you move the 5x to the right making the equation 3y=-5x + 3, then you divide everything by 3. You then find the other info by knowing y=mx+b which means m=slope and b = y intercept
