C :) brainiest? This is correct because I did the math lol
Answer:
25
simple, when you add another number into the sequence, it is increased by 1 per each number...
Hello :
| -4-√2i | = √((-4)² +(-√2)²) =√(16+2) =√18 = √(9×2) = √9 × √2 = 3<span>√2.. (answer B)</span>
Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)
Answer:
7.8 feet
Step-by-step explanation:
The shadow, the ground and the distance between the top of the tree and end of the shadow form 2 right-angled triangles which are similar.
So corresponding sides are in the same ratio. Therefore:-
40 / 12 = 26/x where x is the length of shadow cast by the smaller tree.
40x = 12*26
x = (12*26) / 40
= 7.8 feet
