Hello!
The formula for the area of a triangle is a=1/2bh. Our area is 10. This means that it was half of 20. 20/5 is 4.
The basis is is four square inches.
Hope this helps!
Answer:
the first one
Step-by-step explanation:
Think of it this way. If it needs to be greater than -11, that means there is some kind of restraint. that would be in this situation, its under a square root. if you plug in -11, it should equal 0, so it has to be x+11 under square root. The second one wouldn't work since that would make it square root of -22 and thats imaginary, same thing with all the others, when you plug in -11, the last 3 would come negative. the first one is the only one that cancels the negative and gives you 0
X= 6 is your answer I know the answer but I’m not sure how to explain by typing
Answer:
a: 11/105
Step-by-step explanation:
Simplify the following:
12/35 - 5/21
Put 12/35 - 5/21 over the common denominator 105. 12/35 - 5/21 = (3×12)/105 + (5 (-5))/105:
(3×12)/105 + (5 (-5))/105
3×12 = 36:
36/105 + (5 (-5))/105
5 (-5) = -25:
36/105 + (-25)/105
36/105 - 25/105 = (36 - 25)/105:
(36 - 25)/105
| 3 | 6
- | 2 | 5
| 1 | 1:
Answer: 11/105
Anytime you subtract a negative number, it changes it to adding a positive number.
-2 + 0.7
Since we are adding, we will have an arrow going to the right
-2 + 0.7 = -1.3
Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3
Best of Luck!
