Answer:
-4 or -9
Step-by-step explanation:
-a^2-13a-36=0
(-a-4)(a+9)=0
-a-4=0
a+9=0
a= -4, -9
This pattern is adding the next odd number, starting with 3. For example, we can use the first few numbers:
1 + 3 = 4
4 + 5 = 9
9 + 7 = 16
This means that when we reach 49, we have to add 17 into it to get the answer of 66.
Answer:
7,12.2
Step-by-step explanation:
100+49=149
√149≈12.2
x^2+49=100
x^2=51
=7
