Answer:
D
(4y-5)(3x-5)
Step-by-step explanation:
12xy -15x -20y +25
I will factor by grouping
12xy -15x -20y +25
Factor out 3x from the first group and -5 from the second group
3x(4y-5) -5(4y-5)
Now factor out (4y-5)
(4y-5)(3x-5)
Answer:
24 cm
Step-by-step explanation:
The altitude from the centre to the chord is 5 cm and bisects the chord.
The radius of the circle is 26 cm ÷ 2 = 13 cm
There is a right triangle formed with legs 5 and x ( x is half the chord )
The hypotenuse is the radius, then using Pythagoras' identity
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = 
= 12
Then
length of chord = 2x = 2 × 12 = 24 cm
Answer:
C
Step-by-step explanation:
You know that if its < or >, the line is - - - -, not a fully dark line.
So it would be either A or C
Plot in some numbers for x
Less than would be to the left.
So it wouldn't be A, leaving us with C
