Mathematics
1 answer:
Alla [95]3 years ago
4 0

Answer: B

Step-by-step explanation: You make the values in the parentheses equal to zero.

(X + 3) = 0

X = -3

A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.

How can I solve these problems
KATRIN_1 [288]

Answer:


Step-by-step explanation:

Easy the three angles of a triangle equal 180 degrees

so 60+75 = 135 --> 180-135=

1) 145

2) 35

3)  no since the tops a 100 and its a Isosceles triangle two corners left it be 40 for each corner

4) 34 for both x's cause 34+34+112. = 180

5) 180- 120= 60- 10 = 50/4 is (12.5)= x

6) x = 15 cause it be 120- 60 to get 60

Hello can you help me with this?

Answer:

x = 25.5

Step-by-step explanation:

suppose RS and MQ are parallel the sum of angle MRS and RMN would be 180 degrees

2x + x + x 78 = 180 add like terms then subtract 78 from both sides

4x = 102 divide both sides by 4

x = 25.5
