Factoring x2+5x-1
The first term is, x2 its coefficient is 1 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is 5 .
-1 + 1 = 0
Conclusion : Trinomial can not be factored
Final result :
x2 + 5x - 1
This is what did but I not sure it's right?!
Answer:
512 in³
Step-by-step explanation:
The height perpendicular to the base is the leg of a right triangle with hypotenuse 10 in and other leg 8 in. Using the Pythagorean theorem, we can find it as ...
h² +8² = 10²
h² = 100 -64 . . . . . subtract 8²
h = 6 . . . . . . . . . . . . take the square root of 36
Then the volume is found using ...
V = (1/3)Bh = (1/3)(16 in)²(6 in) = 512 in³
The volume is 512 cubic inches.
_____
The 8-inch dimension used above comes from half the distance between the center of one side of the base to the center of the opposite side. (16 in)/2 = 8 in.
Answer:
There are 5 yellow balls
Step-by-step explanation:
40/4 = 10
10/2 = 5
20 and 28 can be divided by 4, so just take the 4 out so the answer should be 4(5x - 7)
The answer is times the 5500 adding the 6600 and as it adds up the box rate to 1.75 the answer is 1.75 insterest rate and 132000 dollars left
