Answer:
12 the answer
Step-by-step explanation:
Answer: It is one-half the area of a rectangle with sides 2 units × 3 units.
It is twice the area of a square of side length 3 units.
It is one-half the area of a square of side length 3 units.
Step-by-step explanation:
The sequence is alternatingly decreasing and increasing.
3 - 9 = -6
-6 + 18 = 12
12 - 8 = 4
4 + 16 = 20
Therefore, next term will be:
20 - 7 = 13
Answer:
I guess it would be 36?
Step-by-step explanation:
<span>10x+y=19
when x = 10:
substitute with x=10 into the equation given:
10(10) + y = 19
or:
100 + y = 19
bring 100 to the other side to be -100
y = 19 - 100
y = -81
That's it
