Answer: 9a-9b-6
7(3a−2b)+5b−3(4a+2)
Distribute:
7(3a−2b)+5b−3(4a+2)
=(7)(3a)+(7)(−2b)+5b+(−3)(4a)+(−3)(2)
=21a+−14b+5b+−12a+−6
Combine Like Terms:
=21a+−14b+5b+−12a+−6
=(21a+−12a)+(−14b+5b)+(−6)
=9a+−9b+−6
Answer:
The statistical analysis that is appropriate for her design is : one way within groups analysis of variance or ANOVA.
Step-by-step explanation:
The statistical analysis that is appropriate for her design is : one way within groups analysis of variance or ANOVA.
In ANOVA, the researchers can reduce the within-groups variability, by keeping the same number of participants in each group.
Answer:
I believe the correct answer from the choices listed in the image is the second option. The statement that allows us to conclude that line m and line n are parallel would be that angle 2 and angle 7 are equal. They are alternate exterior angles. Hope this answers the question.
Answer:
a. 0.69x + 0.14
b. 5.67 - 30.48a
c. 1.1x - 3.01y
Step-by-step explanation:
a) 2.56x + 0.14 − 1.87x
<em>To simplify this algebraic expression, you start by collecting like terms;</em>
2.56x − 1.87x + 0.14
<em>Then perform arithmetic operation</em>
0.69x + 0.14
b) 7.32a + 2.1 (2.7 − 18a)
<em>Here; first, the bracket must be opened</em>
<em>To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with</em>
7.32a + 2.1 * 2.7 − 2.1 * 18a
7.32a + 5.67 - 37.8a
<em>Then, you collect like terms</em>
7.32a - 37.8a + 5.67
<em>Then perform arithmetic operation</em>
-30.48a + 5.67
<em>Rearrange</em>
5.67 - 30.48a
c) 0.12x + 0.34y + 0.98x − 3.35y
<em>Here, you start by collecting like terms</em>
0.12x + 0.98x + 0.34y − 3.35y
<em>Then perform arithmetic operation</em>
1.1x - 3.01y
