Answer:
9.5
Step-by-step explanation:
Using the pythagorean theorem a^2+b^2=c^2, we can say that 3^2+b^2=10^2.
Simplify and you get 9+b^2=100. Subtract 9 from both sides and you get b^2=91. When you take the square root you get 9.53939... round to the nearest tenth and the missing side is 9.5.
Your greatest common factor is 14.
14 * 1 = 14
14 * 2 = 28
14 * 4 = 56
Answer:
Step-by-step explanation:
Given that,
We know that, 
So,
So,
So, the value of the given expression is equal to
Solving for x
Since x<span> is on the right hand side of the </span>equation<span> switch the sides so it is on the left hand side of the </span>equation<span>.
</span><span>2x+yi=−14−3i
</span>
Since <span>yi</span><span> does not contain the </span>variable<span> to solve for move it to the right-hand side of the </span>equation<span> by subtracting </span><span>yi</span><span> from both sides.
</span><span>2x=−yi−14−3i
</span>Divide<span> each </span>term<span> in the </span>equation<span> by </span><span>2.
</span><span>x=−<span><span>yi/</span>2</span>−7−<span><span>3i/</span>2
Solving for y
</span></span>Since y<span> is on the right hand side of the </span>equation<span> switch the sides so it is on the left hand side of the </span>equation<span>.
</span><span>2x+yi=−14−3i
</span>Since <span>2x</span><span> does not contain the </span>variable<span> to solve for move it to the right hand side of the </span>equation<span> by subtracting </span><span>2x</span><span> from both sides.
</span><span>yi=−2x−14−3i
</span>Divide<span> each </span>term<span> in the </span>equation<span> by </span><span>i.
</span><span>y=2xi+14i−3
</span>x=−yi/2−7−3i/2
y=2xi+14i−3
