For this case we have the following expression:
Applying distributive property to the terms within parentheses we have:
We add similar terms on both sides of equality considering that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
We add 7.5x to both sides of equality:
We subtract 72 from both sides of equality:
We divide between 3 on both sides of equality
ANswer:
Distributive property
Add similar terms
Equality property of the sum
Equality subtraction property
Equality property of the division
Answer:
y=0
Step-by-step explanation:
A slope of 0 is a horizontal line.
Answer:
x=16
Step-by-step explanation:
If the triangles are similar then their sides are in proportion.
Set the proportions 20/(3x+8)=(x-1)/(x-1+27)
solve for x,
cross multiply
20(x+26)=(x-1)(3x+8),
distribute
20x+520= 3x² +8x-3x-8,
combine like terms
3x²-15x-528=0
solve using quadratic formula
x=16 and x= -11 reject because we cannot have negative measurements
Answer:
A. Knowing that 6^2 + 8^2 = 10^2, draw the 6 cm side and then the 8 cm side with a right angle between them. The 10 cm side will fit to form a right triangle.
