X² + 6 = 87
<u> - 6 - 6</u>
x² = 81
x = <u>+</u>9
x = 9 U x = -9
The solution set is equal to D. {<u>+</u>9}.
Answer:
Step-by-step explanation:
So to do this you would add the two numbers together first. 50.6 +5.8+56.4. The length is 6 times this new amount, so you would divide it by 6 to get your answer. 56.4/6= 9.4. Therefore, the answer would be 9.4
Answer:
Step-by-step explanation:
A quadrilateral with 4 same-length sides is a <em>rhombus</em>.
(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)
__
Adjacent angles are supplementary, so ...
x° = 180° -110° = 70°
Sides are the same length, so ...
2y = y+5
y = 5 . . . . . subtract y
_____
If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.
Scientific notation is basically a short cut to write numbers with a lot of zeros in them. The difference between 3^8 and 3*10^8 is that the first is 3 multiplied by itself 8 times, and the second is 3 being mulitplied by 10^8. I hope this helps.
