Answer:
(a) 6ab² - 8a²b + 3ab
Step-by-step explanation:
Given: 5ab² - 12a²b + 3ab + ab² + 4a²b
In this question, we will be combining like terms.
What are like terms?
Like terms are terms with the same variables and power. For example, 2x and 4x, as well as 2a² and 4a².
Combine like terms:
5ab² - 12a²b + 3ab + ab² + 4a²b
(5ab² + ab²) + (-12a²b + 4a²b) + 3ab
6ab² - 8a²b + 3ab
Answer:
C
Step-by-step explanation:
compare which numbers are bigger on the chart and then compare which lines are taller/shorter than each other on the bar graph
The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
Answer:
about 37, so probably B
Step-by-step explanation:
tg a = 3/4
tg a = 0.75
F(x)=(-1)^2+3
f(x)=1+3
f(x)=4
The slope is 0 because 4 is a constant.
