Hey there

The correct answer is:
f(x+5)=(x+5)^2+3(x+5)-10
f(x+5)=x^2+10x+25+3x+15-10
f(x+5)=x^2+13x+30 and f(x+5)=x^2+kx+30 so
k=13
Now factor x^2+13x+30
Find j and k such that jk=ac=30 and j+k+b=13 so j and k are 10 and 3 so
(x+3)(x+10)
So the two zeros occur when x=-3 and -10 the smallest of which is:
x=-10

Answer: 14
Step-by-step explanation:
when you multiply 9 by 14 you get the answer 126.
So it takes 14 nines to get 126.
Answer:
B. 9(4+8)
Step-by-step explanation:
Start by simplifying the original expression:
36+72=108
Now, let's try each answer choice:
A. 18(2+3)
Add the numbers in the parentheses:
18(5)=90 --> wrong!
B. 9(4+8)
Add the numbers in the parentheses:
9(12)=108 --> correct!
C. 3(10+24)
Add the numbers in the parentheses:
3(34)=102 --> wrong!
D. 2(19+27)
Add the numbers in the parentheses:
2(46)=92 --> wrong!
Therefore the answer is B. 9(4+8)
Answer:
x = 10
Step-by-step explanation:
45x - 15x = 300
Combine like terms
30x = 300
Divide each side by 30
30x/30 = 300/30
x = 10
2x + 1.5 y = 985
y = students
x = adults
x + y = 578
*-2 * -2
-2x - 2y = -1156
2x + 1.5y = 958
-2x - 2y = -1156 (add these together)
-0.5 y = -198
*-2 *-2
y = 396
x + 396 = 578
x = 182
396 students
182 adults
