Answer:
(x - 13) and (x + 3)
Step-by-step explanation:
Given
x² - 10x - 39
Consider the factors of the constant term (- 39) which sum to give the coefficient of the x- term (- 10)
The factors are - 13 and +3, since
- 13 × 3 = - 39 and - 13 + 3 = - 10, thus
x² - 10x - 39 = (x - 13)(x + 3) ← in factored form
Diameter is twice the radius. A=πr^2.
First, solve for r:
32.15=πr^2
<em>*Divide both sides by </em>π*
10.2337=r^2
<em>*Take the square root of both sides*</em>
3.199=r
Multiply the radius by 2:
3.199*2=6.398
D. 6.4 feet
Hope this helps!!
The red line has a y-intercept of -4, so the linear equations of choices A and C can be eliminated.
The numerator of the rational expression of choice B will not be zero when x=4, so that choice can be eliminated. (That is, check to see if the point (4, 0) satisfies the equation. It does not.)
The problem requirements are met by the last choice:
d y = x minus 4, over x plus 2
y = x − 4
Answer:
Step-by-step explanation:
Well if you want the answers there are 3 different ways
x = 12/5
or
x = 2.4
You can find out the answer by subtraction 32 by 9. This equals 23. 23 + 9 = 32. Therefore, z = 23. Hope this helps!
