That's Intersecting Secants, and we get
EC × ED = EB × EA
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
8 = 4 x
x = 2
Check: 3(14)=42 6(7)=42 good
Answer: 2
Answer:
x = -2
Step-by-step explanation:
-9x + 1 = -x + 17
To solve this equation
Note if there is more than one variable like x, y, or z
Also note the power of the variables, for example, x^2 or y^3
In this equation, there is only one variable which is x and it's also in the power of 1 ie x
Step 1 : rearrange according to like terms
-9x + x = 17 - 1
( don't forget that the sign always change on crossing an equals to, either + to - or - to +
-9x + x (also means 9 - 1 but only carries a negative sign)
= - 8x = 16
Dividing both sides by -8 to get the value of x
-8x / 8 = 16 /- 8
x = 16/ -8
x = -2
Answer:
