The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.
Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
Answer: OPTION D.
Step-by-step explanation:
The formula for calculate the circumference of a circle is:
Where <em>r</em> is the radius.
The formula for calculate the area of a circle is:
Where <em>r</em> is the radius.
Solve for <em>r</em> from to calculate it:
Subsitute the radius into . Then:
Answer:
10 times the value
Step-by-step explanation:
The value of 8 in the hundreds place (800) is 10 times the value of 8 in the tens place (80).
I figured this out by dividing 800 by 80 = 10.
