Answer : 
(1) 
Use FOIL method to mulitply (3x – 5)(3x – 5)
(2) 
Use FOIL method to mulitply (3x - 5)(3x + 5)
(3) 
Use FOIL method to mulitply -(3x + 5)(3x + 5)
(4) 
Use FOIL method to mulitply -(3x + 5)(3x - 5)
So equation 2 is true
Answer:
gradient is 8 and y intercept is 0
Step-by-step explanation:
y=mc+b
take one pair of corridants:
8=1m+b
m=8 (change in y values/changes in x values)
8=1x8+b
do the equation
y=0
Have a nice day!!!!!!!!! :-)

Answer:
5 units
Step-by-step explanation:
If point T is on the line segment SU, then ST + TU = SU.
Given
TU = 4x + 1
SU = 8
ST = 3x
To get TU, we need to get the value of x first. To get x, we will substitute the given parameters into the formula;
3x+4x+1 = 8
7x+1 = 8
subtract 1 from both sides
7x+1-1 = 8-1
7x = 7
divide both sides by 7
7x/7 = 7/7
x = 1
Substitute x = 1 into the length TU
Since TU = 4x+1
TU = 4(1)+1
TU = 5
Hence the numerical length of TU is 5 units

So,
y = mx + b is the slope-intercept form.
"m" represents the slope. It will allow you to find additional points on the specified line by determining the "rise" and the "run." The "rise" means vertical movement, and the "run" means horizontal movement.
"b" represents the y-intercept, which is the point on the line where x = 0. When x = 0, the line crosses, or intercepts, the y-axis.
