The answer is x = 0, -13/2
Answer:
AB = 5
BC = 12
AC = 13
Step-by-step explanation:
A rectangle is a quadrilateral and therefore, opposite sides are parallel and congruent to each other. Thus:
AB = CD = 12
AB = 12
BC = AD = 5
BC = 5
AC is a diagonal of the rectangle, use Pythagorean theorem to find it's length as follows:
AC² = AD² + CD²
Plug in the values
AC² = 5² + 12²
AC² = 169
AC = √169
AC = 13
The outer exponent is 4 so there will be 5 terms all together. By rules of exponents
C(4,0)(3^4)(2^0)(x^8)(y^0) + C(4,1)(3^3)(2^1)(x^6)(y^3) + C(4,2)(3^2)(2^2)(x^4)(y^6) + C(4,3)(3^1)(2^3)(x^2)(y^9) + C(4,4)(3^0)(2^4)(x^0)(y^12)
The coefficient of the 3rd term: C(4,2)(3^2)(2^2) = 6 x 9 x 4 = 216
Answer:
152.6 hours
Step-by-step explanation:
Distance = Speed × Time
Time = Distance/Speed
Santa's sleigh covered a total distance of 5797 kilometres averaging a speed of 38 km/h in snow storm conditions
Hence: Time Santa spent in snow storms is calculated as:
5797km ÷ 38 km/h
= 152.55263158 hours
Approximately = 152.6 hours
A) 324
I divided 240 by 20 to get how much it would cost per kg. For each KG the cost is $12. So then I multiplied 12 by what was asked of you (27) which lead me to the answer of 324.
B) 512
Same concept as A. Divide to get how much gasoline is used per mile. That was 4 miles per 1 gas. Multiply 4 by whatever you have been asked for (128). That leads you to 512.
C) 648
Same concept as above.
D) 5,445
