1)
log 98 = log( 7 * 14 ) = log 7+ log 14= h + j ;
2)
log 175 = log ( 5^2 * 7 ) = log 5 ^ 2 + log 7 = 2 * log 5 + log 7 = 2i + h ;
3)
log 2 = log ( 14 / 7 ) = log 14 - log 7 = j - h ;
4)
log 245 = log ( 7^2 * 5 ) = log 7 ^2 + log 5 = 2 * log 7 + log 5 = 2h + i ;
Answer:
B
Step-by-step explanation:
3.4 x -3.4= -11.56
3.4 X 3.4 = 11.56 YES
-3.4 X -3.4 = 11.56
-3.4 X 3.4 = -11.56
Answer:
Perimeter of triangle is 38 inches
Step-by-step explanation:
Figure show triangle with sides of (21-x), (2x-3)and(x+5)
Here, The pool balls are arranged in triangle in symmetry.
Hence, Triangle is equilateral triangle.
For equilateral triangle,
Sides are equal in length (21-x) = (2x-3) = (x+5)
Take (2x-3) = (x+5)
2x-3=x+5
2x-x=5+3
x=8.
Now,Perimeter of triangle is summation of all of the sides.
= (21-x) + (2x-3) + (x+5)
= (21-8) + (2(8)-3) + (8+5)
= 13 + (16-3) +12
= 13+13+12
= 26+12
= 38 inches
Answer:
i) 3
ii) 5
Step-by-step explanation:
i) -2x -5 = -11
-2x = -11 + 5
-2x = -6
x = -6 ÷ -2
= 3
ii) -2x + 6x - 8 = 12
-2x + 6x = 12 + 8
-2x + 6x = 20
(-2 + 6) x = 20
4x = 20
x = 20 ÷ 4
= 5
The answer is 6.89. hope this helps!
