Answer:

3(x)^3 + 2(x)^2 + 22x - 15

Step-by-step explanation:

(3(x)^2 + 2x - 3) (x + 5)

=>(3(x)^2 + 2x - 3) (x) + (3(x)^2 + 2x - 3) (5)

=>3(x)^3 + 2(x)^2 - 3x + 15x + 10x - 15

=>3(x)^3 + 2(x)^2 + 22x - 15

The diameter of Jupiter is 142.984 Km. The surface area of Saturn is 59.9% the surface area of Jupiter. What is Saturn's diamete
Otrada [13]
Suppose that both planets are spherical. radius of Saturn =142984/2=71,492

Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10

Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10

Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km

WILL GIVE A 5 STAR RATING A THANKS A BRAINLIEST and 12 points.
Sauron [17]

since there are 180 degrees in a triangle so :


65+72+y=180  add like terms

137 + y=180 now subtract 137

y= 180-137

y=43 degrees

Find the surface area of the cube.
Mrac [35]
<h3><u>Given</u>:-</h3>

\rightarrow Side(a) of the cube = \sf{\frac{1}{3}ft}.

<h3><u>To Find</u>:-</h3>

\rightarrow Surface Area of the cube with side \sf{\frac{1}{3}ft.}

<h3><u>Formula Used</u>:-</h3>

\rightarrow Surface area of cube = \sf{6a^2}

<h3><u>Solution</u>:-</h3>

\rightarrow Surface area of cube = \sf{6a^2} (putting the value of a from the above given)

\rightarrow \sf{=\:6×(\frac{1}{3})^2}

\rightarrow \sf{=\:6×\frac{1}{9}}

\rightarrow \sf{=\:\frac{6}{9}}

\rightarrow \sf{=\:\frac{2}{3}ft^2}

Therefore, surface area of the given square = \sf{=\:\frac{2}{3}ft^2}
