Answer: 30 + 45 = 15(2 + 3)
Step-by-step explanation:
The greatest common factor for 30 and 45 will be gotten as follows:
Factor of 30 = 2 × 3 × 5
Factor of 45 = 3 × 3 × 5.
GCF = 3× 5 = 15
Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:
30 + 45 = 15(2 + 3)
Answer:
7
Step-by-step explanation:
15-8=7
We know that with a straight line, the resulting angle is 180.
So, knowing this:
6x+12+5x+3=180
Solve for x
11x+15=180
11x=165
x=15
Plug x back into your respective angles
Angle 1: 6(15)+12=102 degrees
Angle 2: 5(15)+3=78 degrees
Therefore angle 2 is 78 degrees.
Answer:
no,it isnt,
Step-by-step explanation:
pythagoras property of right angle:
height sq + base square = hypotenuse sq
5*2+12*2=14*2
25+144=196 which is wrong
X equals 3
Explanation:
X equals 2 because 3 plus 3 is 6
