Answer:
That is true. More information below.
Step-by-step explanation:
A prime number has to have only two factors: 1 and itself. 1 only has one factor (itself) so it is, as you were saying, neutral.
Answer:
x=60
Step-by-step explanation:
this is an isosceles triangle. so angle D and F are equal. D= x and F=x. so 58+x+x=180
2x+58=180
2x=122
x=60
Y = 6 x² + 12 x - 10= 6 ( x² + 2 x ) - 10 = 6 ( ( x² + 2 x + 1 ) - 1 ) - 10=
6 ( x + 1 )² - 6 - 10 = 6 ( x + 1 )² - 16 ( vertex form)
Number 1 and 3 mate your welcome
#10 ) 6/x = 5/11 OR 6/x = 9/19.8
5x = 66 9x = 118.8
x = 13.2 x = 13.2
#11 ) original photo is 5 inches by 7 inches, multiply that , = 35 ( area of original photo )
new photo is "3 times larger" so 5 become 15 and 7 become 21 , multiply that which gives you 315 (area of enlarged photo )
take the enlarged photo's area divided by the original photo's area which gives you 9
#12 ) 6/8 = x/12
72 = 8x
9 = x
#13 ) set equal to find segment TR : 4/10 = 6/x
4x = 60
x = 15
then find the perimeter of triangle by P = a + b + c
P = 10 + 12 + 15
P = 37
