Answer:

x = - $\frac{14}{3}$

Step-by-step explanation:

Given

$\frac{3}{4}$ (x + 5 $\frac{1}{2}$ ) = $\frac{5}{8}$

Multiply both sides by 8 to clear the fractions

6(x + 5 $\frac{1}{2}$ ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = $\frac{-28}{6}$ = - $\frac{14}{3}$

Find the perimeter of triangle PQR. Round your answer to the nearest tenth.

BabaBlast [244]

We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.

Side PQ = $\sqrt{ (6-(-2))^{2}+ (1-1)^{2} }=8$

Side QR = $\sqrt{ (4-6)^{2}+ (-3-1)^{2} }=4.5$

Side RP = $\sqrt{ (2-(-4))^{2}+ (-3-1)^{2} }=7.2$

So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7

You probably misplaced the digits in option A. The correct answer is 19.7 units.

What conclusions can you draw about the roots of the equation x^3+x^2-2x+12=0

nexus9112 [7]

Answer:

x=-3

Step-by-step explanation:

If x=-3, then

x³+x²-2x+12=-27+9+6+12=-27+27=0

If this is true, then x+3 is a factor. So:

x³+x²-2x+12/x+3=x²-2x+4

So the factors of x³+x²-2x+12 are:

(x+3)(x²-2x+4)

((x²-2x+4) has no real roots)........
