5.8 x 2.19
= (5.00 + 0.80) x (2.00 + 0.19)
= 5.00*2.00 + 5.00*0.19 + 0.80*2.00 + 0.80*0.19
= 10.00 + 0.95 + 1.60 + 8/10 * 19/100
= 10.00 + 0.95 + 1.60 + (8*(10+9))/1000
= 10.00 + 0.95 + 1.60 + (80+72)/1000
= 10.00 + 0.95 + 1.60 + 152/1000
= 10.000 + 0.950 + 1.600 + 0.152
= 11.600 + 0.950 + 0.152
= 12.550 + 0.152
= 12.702
Hope this helps!
<u>ANSWER</u>
a. 12 units
<u>EXPLANATION</u>
According to the altitude theorem, RT which is the altitude, is equal to the geometric mean of TQ and TS, the segments created by the foot of the altitude on the hypotenuse.
This implies that:

From the diagram, TQ=16 and TS=9.
We substitute these values and solve for x.



Therefore x is 12 units.
The correct answer is A
Hello from MrBillDoesMath!
Answer:
-52. None of the provided choices is correct
Discussion:
Following the usual order of math operations none of the provided answers is correct. The answer is
2*3 + 4- 62 = => * before + and -
(2*3) + 4 - 62= => 2*3 = 6
6 + 4 -62 = => 6 + 4 = 10
10 - 62 =
-52
