Explain how algebra tiles represent like terms and zero pairs

Mathematics

Katena32 [7]3 years ago
7 0
Well if you have a problem like -6 + 7, then you can use one color of algebra tiles(atls) for the negative and another color for positive. Take yellow for negative and red for positive for an example. You have 6 yellow and 7 reds. You want to make as many pairs of one red and one yellow. You can make a total of 6 pairs and a red left over. Since red is positive an there is only one, your answer is 1.

Hope i helped

<span>Often the university sites exist primarily for internal use, listing equipment and demos available to physics professors teaching large sections of introductory courses. They usually give lists of required equipment, they don't always give much information about setup, effective presentation and explanation of the physics.</span>

Find the measure of two complementary angles, a and b, if m a = 7x + 4 and m b =4x + 9
VashaNatasha [74]
Complentary angles add to 90 degrees
a and b are complentary
a+b=90

a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7

m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37

angle a measures 53 degrees
angle b measures 37 degrees
