Answer:
RT = 12 units
Step-by-step explanation:
From the figure attached,
ΔSRQ is right triangle.
m∠R = 90°
An altitude has been constructed from point T to side SQ.
m∠RTQ = 90°
By applying geometric mean theorem in triangle SRQ,
![\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BRT%7D%7D%7B%5Ctext%7BST%7D%7D%3D%5Cfrac%7B%5Ctext%7BTQ%7D%7D%7B%5Ctext%7BRT%7D%7D)
![\frac{x}{9}=\frac{16}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B9%7D%3D%5Cfrac%7B16%7D%7Bx%7D)
x² = 16 × 9
x² = 144
x = √144
x = 12
Therefore, length of altitude RT is 12 units.
Answer:
y = x² - 2x - 8
Step-by-step explanation:
Given
y = (x - 4)(x + 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 2) - 4(x + 2) ← distribute parenthesis
= x² + 2x - 4x - 8 ← collect like terms
= x² - 2x - 8 ← in standard form
Answer:
I got (3> -15 3>3(-2s) )
Step-by-step explanation:
I use symbolab it really helps :)
Answer:
The only option 2 which gives the same values for m=1 and m=4 in both the expressions. ∴ Option 2 is correct.
