Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation
<span>x</span>²<span> - 10x = -18
So then you add (b/2)</span>²<span>, which is 25, to both sides, to get
</span><span>x</span>²<span> - 10x + 25 = 7
</span><span>After this, you factor.
</span><span>(x-5)(x-5) = 7
</span><span>Then you simplify.
(x-5)</span>²<span> = 7
Then you solve for x.
</span>√(<span>x-5)</span>²<span> = </span>√7
x-5 = (+ or -)√7
~ x= 5 (+ or -)√7 ~
Hope this helps!
Answer:
the number of meters is smaller than 8
Step-by-step explanation:
A meter is 100 times the length of a centimeter, so it takes a factor of 100 fewer of them to have the same length.
8 cm = 0.08 m
0.08 is a smaller number than 8. The number of meters is less than the number of centimeters (by a factor of 100).
Answer:
Step-by-step explanation:
= 30°
Answer:
B.
Step-by-step explanation:
Because if you subtract 19x and 18 from each side it wont be 0=0, in other equatins there is infinity solutions
