Combine like terms.

2x + 6 + 6x - 1

8x + 5

I think you are supposed to combine alike terms, so 2x + 6 + 6x - 1 would be combined to be 8x + 5.

HELP ME WITH THESE THANKS :)!
kvv77 [185]

Answer:

50; 72; 8; 57.9

Step-by-step explanation:

1. sqrt((30/2)^2 + (20)^2) = sqrt(15^2 + 20^2) = sqrt(225 + 400) = sqrt(625) = 25 (radius) * 2 = 50 (diameter)

2. 360 (degrees in a circle)/5 (sides in a pentagon) = 72 degrees

3. 360 (degrees in a circle)/x (sides) = 45 --> 360/45 = x --> 8 sides = x

4. sqrt(7^2 + (12/2)^2) = radius --> sqrt(49 + 36) --> sqrt85 * 2pi = circumference --> 57.9281062 = circumference --> 57.9

I NEED HELP ON 2 PLEASEEEEEEEEE
Leto [7]

Answer:

294

Step-by-step explanation:

Scale factor is 3.5 (If you go from the smaller image to the bigger image).

7 x 3.5 = 24.5 feet

since the question is asking you for the answer in inches you have to multiply 24.5 by 12 which gives you 294

According to the fundamental theorem of algebra, how many zeros does the function f(x) = 15x17 + 41x12 + 13x3 − 10 have?
liberstina [14]
The fundamental theorem of algebra states that a polynomial of degree has exactly n roots (including complex and multiple).
The degree of a polynomial is the highest (non-negative) exponent of the polynomial, in this case is 17 from the term 15x^17.

Which of the following is the solution to the inequality below ? -6/5(4-x)<_-4(X+1/2)
LuckyWell [14K]

Answer:

The answer is the option D

x\leq 7/13

Step-by-step explanation:

we have

-\frac{6}{5}(4-x)\leq -4(x+\frac{1}{2})

Multiply by -5 both sides

6(4-x)\geq 20(x+0.5)\\24-6x\geq20x+10\\24-10\geq 20x+6x\\14\geq 26x

Rewrite

26x\leq 14\\x\leq 14/26\\ x\leq 7/13
