Answer:
-10
Step-by-step explanation:
4+-5 is the same as 4-5 =-1
7--3 is the same as 7+3 =10
-1 * 10 = -10
1/2<0.55<5/7
This is the order from least to greatest
Answer:
The value of x =10°
Step-by-step explanation:
Check attachment for solution.
Triangle theorem: the sum of the opposite interior angle is equal to the exterior angle.
<JKL+<LJK=<KLM
2x+14+3x+15=7x+9
Collect like terms
2x+3x-7x=9-14-15
-2x=-20
Divide both side by -2
x=10°
Answer:
Step-by-step explanation:
2x²-2x-12 = 2 (x²-x - 6)
but : x²-x - 6 = x² - 2(1/2)x +(1/2)² - (1/2)² - 6
= ( x - 1/2)² - 1/4 - 6
= ( x - 1/2)² - 25/4
x²-x - 6 = ( x - 1/2)² - (5/2)²
by identity ; a² - b² = (a - b ) ( a +b)
x²-x - 6 = ( x - 1/2 - 5/2) ( x - 1/2 +5/2)
x²-x - 6 = (x - 3) (x +2)
so : 2x²-2x-12 =2(x - 3) (x +2) = (2x-6)(x+2) .......(factored form)
now : 2x²-2x-12 = 0 : 2x - 6 = 0 or x+2 = 0
x= 3 or x = - 2 two solutions
Answer:
Step-by-step explanation:
So, formula to be used is:
Average area of cross section is = volume/distance between plates.
Volume = 4343/22 = 197.4 square feet.
