Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2

Answer:
lateral area = 180π in²
Step-by-step explanation:
The lateral area is the surface of the cone only.
perimeter of base = 12 x 2 = 24π in
Surface Area = 1/2 perimeter x slant height
SA = 1/2 x 24π x 15 = 180π in²

Joey went to the county fair last weekend. When he got there, he had to walk 1/2 of a mile from the car to the entrance. Then he walked 11/16 of a mile to the carnival rides and 1/2 of a mile from the carnival rides to the farm animal show. Next, he walked 3/4 of a mile back to the car. How many miles did Joey walk in all?
Answer:
39/16 or 2 7/16 miles
Step-by-step explanation:
find the common denominator between all fractions (16).
1/2 = 8/16
3/4 = 12/16
8 + 11 + 8 + 12 = 39
Therefore, Joey walked 39/16 or 2 7/16 miles in total

Answer:
Since 4 is the largest number its the hypotenuse. The two 3s are equal so they are interchangeable so it doesn't matter where you put them. If its a right triangle the hypotenuse is opposite the right angle.
