Answer:
23°
Step-by-step explanation:
By interior angle sum postulate of a triangle.
x = 180° - ( 124° + 33°)
x = 180° - 157°
x = 23°
540-35x= y
540 is the amount she has minus 35 and x is the weeks she withdrawn the money and y is the answer.
Remember to follow PEMDAS, and to only combine terms with like variables.
First, distribute the 2 to all terms within the parenthesis:
2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t
3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.

Answer:
9
Step-by-step explanation:
For this problem, you would use the GCF
Find the GCF of 45, 81, 63
GCF(45, 81, 63) = 9
45 = 9 * 5
81 = 9 *9
63= 9 * 7
Since 5, 9, 7 have no common factors, the GCF has to be 9.
This means that the greatest number of plants he can put in each row is 9.
The number of rows he uses for each plant will (obviously) vary.
f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
