Answer:
Step-by-step explanation:
Let X be the first number.
(X)*(X+2)*(X+4)*(X+6) = 62985
(X^2 + 6X)^2 + 8(X^2 + 6X) = 62985
X = 13, AND X= -19
A. X = 13
(13)(15(17)(19) = 62985
B. X = -19
(-19)(-17)(-15)(-13) = 62985
Answer: subtraction
Reasoning: You need to subtract 3 from both sides first.
Answer:
C. f(-1) =12
Step-by-step explanation:
f(x)= 3x^2+9
Let x=-1
f(-1) = 3(-1)^2 +9
= 3(1)+9
= 3+9
= 12
f(-1) =12
Answer:
200
Step-by-step explanation:
2. Using the external angle of a triangle theorem.
6x - 17 = 3x - 11 + 2x + 11
6x - 5x = 17
x = 17
So m angle K = 2(17) + 11
= 45 degrees answer
3. The diagonals are both medians of the triangle so the 2 parts are in the ratio 2:1 so 3:x = 2:1 and x = 1.5 answer
2:1
