Examples of conjunctions are and, but, or, yet. So your answer would be A. I hope this helped. :)

A park has a grinkgo tree a dogwood tree and 2 blue spruce trees the blue spruce trees are 8 years old the grinkgo tree is 2 yea

enot [183]

Answer:

The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old

Step-by-step explanation:

Let

x -----> the age of the grinkgo tree

y -----> the age of the dogwood tree

z -----> the age of the blue spruce tree

we know that

$x=3y-2$ ------> equation A

$z=8$ ----> equation B

$x=\frac{1}{2}(y+2z)$

substitute the value of z

$x=\frac{1}{2}(y+2(8))$

$x=\frac{1}{2}(y+16)$ -----> equation C

equate equation A and equation C and solve for y

$3y-2=\frac{1}{2}(y+16)$

$6y-4=(y+16)$

$6y-y=16+4$

$5y=20$

$y=4$

Find the value of x (equation A or equation C)

$x=3(4)-2=10$

therefore

The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old

Answer:

6 inches

Step-by-step explanation:

Formula for surface area of a cylinder:

$SA=2\pi r^{2} +2\pi rh$

Plug in values and solve for the radius:

$180\pi =2\pi r^{2} +2\pi r(9)\\$

Divide both sides by $2\pi$

$90=r^{2} +r(9)$

Subtract 90 from both sides

$0=r^{2} +9r-90$

Use the quadratic equation to find the roots

$x=(-b$ ± $\sqrt{b^2-4ac})*\frac{1}{2a}$ (sorry for formatting, Brainly doesn't

allow equations with ± in them)

$x=\frac{-9+\sqrt{9^2-4*1*90} }{2(1)}$ and $x=\frac{-9-\sqrt{9^2-4*1*90} }{2(1)}$

$x=\frac{(-9+\sqrt{81+360})}{2}$ and $x=\frac{(-9-\sqrt{81+360})}{2}$

$x=\frac{(-9+\sqrt{441})}{2}$ and $x=\frac{(-9-\sqrt{441})}{2}$

$x=\frac{(-9+21)}{2}$ and $x=\frac{(-9-21)}{2}$

$x=\frac{12}{2}$ and $x=\frac{-30}{2}$

$x=6$ and $x=-15$

We can't have a negative radius, so that leaves us with r=6 in.
