A!!
-2 and 2 are the x values of the coordinates which are 4 units apart, being 4 units in LENGTH
1 and -2 are 3 units apart and them being in the y part of the coordinate it’s 3 units wide
Answer:
+5x+6.
Step-by-step explanation:
Here you can use the foil method.
1. Multiply x by x to get .
2. Multiply x by 3 to get 3x.
3. Multiply 2 by x to get 2x.
4. Multiply 2 by 3 to get 6.
Now, you have to add all those terms to get +3x+2x+6 and you can simplify that to +5x+6.
Let the weight of triangle be x units. You are given that the weight of square is 1 unit.
1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.
2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.
3) If the whole system is balanced, then the weights on left and right sides are equal:
3x+5=2x+7.
Solve this equation:
3x-2x=7-5,
x=2 units.
Answer: option A
Answer:
1/2
Step-by-step explanation:
Since half of them chose to play dress-up, the probability of randomly selecting a child that chose to play dress-up would also be 1/2.
(hope this helps :P)
Answer:
firstly we have to do cross multiplication
a*2= 6*15
2a = 90
a = 90/2
a = 45
hope my answer is helpful to you
