Doubles are adding the same number together, as with 5+5=10.
With doubles +1, the numbers must be in beside each other in counting order going up or down (ex: 4, 5, 6 and 9, 8, 7). Do the SMALLEST number, double it, then add one. So, 9+8 would be 8+8=16, +1=17. You must know your doubles facts before this strategy is useful.
Step-by-step explanation:
Volume= [(20+20) x (20+20) x 100] - (20 x 20 x 100)
=120000cm^3
surface area= 2 x 40 x 100 + 2 x (40 x 40 - 20 x 20) + 4 x 20 x 100
=18400cm^2
Simply combine like terms.
x and 7x make 8x
-1 and 4 and -3 make 0
So, the answer is B. 8x.
When you GRAPH an equation or inequality you plot all of the points that satisfy it.
Answer:
p=1
Step-by-step explanation:
A deck has a combined 52cards.
Given that you're certain to select a red or black card:-
p(red)=>
p(black)=>
Therefore total probability of selection is expressed as:-
