Answer:
The total money raised by two Friends in fundraiser is $ ( 17 d + 15).
Step-by-step explanation:
Money raised by one friend = $ (9 d + 10)
Money raised by other friend = $ (8 d + 5)
Now, Total Money raised together
= Money Raised by friend 1 + Money raised by friend 2
= $ (9 d + 10) + $ (8 d + 5)
= ( 9d + 8d) + ( 10 + 5)
= 17 d + 15
or, Total Money = ( 17 d + 15 )
Hence, the total money raised by two Friends in fundraiser is $ ( 17 d + 15).
Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7
Base angles.
They are congruent
