Answer:
True ( A )
Step-by-step explanation:
4 ( 5 ) - 2 = 2 ( 5 ) + 8
20 - 2 = 10 + 8
18 = 18
This is a correct statement because 18 does equal 18
Final Answer is 4n-32/(n-4)(n+4)
Answer:
a) x =3 and x=5
c) x =-1 and 
i) x =0 and 
Step-by-step explanation:
a)
Given that the quadratic equation
x² - 8x +15 =0
The factors of 15 = 5 × 3
x² - 5x -3x +15 =0
x(x -5) -3(x-5) =0
(x-3)(x-5) =0
x =3 and x=5
c)
3 x² + 10 x +7 =0
⇒ 3x² + 3x + 7x +7 =0
⇒ 3x (x +1) +7(x+1) =0
⇒ (x+1) ( 3 x +7) =0
⇒ x =-1 and
i)
2 x ² + 9 x =0
⇒ x( 2 x + 9) =0
⇒ x =0 and 2 x = -9
⇒ x =0 and
if the figures perimeter is 18 units, and the width of the figure is 5 units. I am guessing the figure is a rectangle
where the width is 5 units, and 2 of the sides have 2 be the same 2 be a rectangle, than the width on each side is 10 units all together
18-10= 8
if the figure is a rectangle then that means there are 2 sides left of equal length so if we divide our current number (8) by 2 then we will have the length of each side (4)
8 divided by 2= 4
width= 5
length= 4
Answer:
For the first question it is 2.
2 x 2 = 4
5 x 2 = 10
4 + 10 - 14 = 0
The second question is -2
-2 x -2 = 4
5 x -2 = -10
4 + -10 + 6 = 0
Hope this helps
