Help please this is geometry

Mathematics
1 answer:
Pepsi [2]3 years ago
3 0

Answer:

14

Step-by-step explanation:

All of the angles are marked as congruent, which means it is an equlateral triangle. This means that all of the sides are congruent too.

Therefore z + 2 = 2z -10

add 10 to each side

z + 12 = 2z

subtract z from each side

12=z

now that we know that, we can plug it back in to either line (it doesn't matter because they're congruent)

line AB is z+2 which is 12+2 or 14

and line CB is 2z-10 which is 2(12)-10 or 24-10 which is also 14

so line CA is also 14 units long.

Please solve the math question: |4x−4(x+1)|=4
alexgriva [62]

Answer:

x has infinite solutions

Step-by-step explanation:

|4x−4(x+1)|=4

Simplify inside the absolute value by distributing the 4

|4x−4x+4|=4

Combine like terms

|4|=4

The absolute value of 4 is 4

4=4

This is always true, so x is all real values

x has infinite solutions

QUESTION - What is -2(3x + 12y - 17x - 16y + 4) simplified? ANSWERS A. -40x + 8y + 2 B. 28x + 8y + 2 C. 28x + 6y + 2 D. -28x - 8
erica [24]

Answer:

28 + 8y - 8

Step-by-step explanation:

According to the problem;

-2(3x + 12y - 17x - 16y + 4)

Collecting like terms;

-2(3x -17x + 12y - 16y + 4)

-2(-14x - 4y + 4)

28 + 8y - 8

None of the options matches the correct answer.

No, he is not correct. The lines are the same, so there are an infinite number of solutions.

When two lines are parallel, then the solution is empty set.
