Hi Braino
Algebra is an easy lesson.It gives egs such as t4 means t times 4.
Also

Answer:
24. a. perimeter=6x-6 or 6(x-1) b. area=2x²+x-28
25. -5x² and 2x are not like terms so you cannot combine them.
Step-by-step explanation:
24. a. perimeter:
add up each side:
(2x-7)+(2x-7)+(x+4)+(x+4)= 6x-6 or 6(x-1)
b. area:
F.O.I.L.:
(2x-7)(x+4)=2x²+8x-7x-28
2x²+x-28
Answer:
ΔABC ≅ ΔQPR
Step-by-step explanation:
if you were to reflect it, they would line up also A ≅ Q because their angles are the same and I know that because of the markings, they both have one arc and B and P both have two arcs meaning they are congruent and C and R both have three arcs so they are congruent.
The general form of the linear equation is,
y = mx + b
where y is the dependent variable, m is the slope, x is the independent variable, and b is the y-intercept.
Substituting the known values,
1. y = 2.6x
where y is the total cost and x is the number of gallons purchased.
2. y = 1.6x + 2
where y is the total weight of the bucket and the golf balls and x is the number of golf balls inside the bucket.
3. P = 2x - (110/150)(x)
Simplifying,
P = 19x/15
where P is the profit and x is the number of pounds of tomatoes brought to the market
4. y = 40x + 80
where y is the total number of enrolled students and x is the number of years
5. y = mx + b
where y is the total number of charge, m is the cost per person, x is the total number of persons and b is the flat fee
