Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
75 ÷ 6 = 12.5 round up to the next whole number... 13
Answer: F.) 7 triangles
Step-by-step explanation:
Congruent means completely equal in side lengths and angles. Think of this weird figure like 4 triangles that are see through and are covering a diamond underneath
Of those 4 "see through triangles", there are 3 equal to ΔABC
Now on the diamond underneath, there is another 4. Its hard to actually explain what I mean, but take two triangles from that dimaond. Theyre gonna be congruent to ΔABC.
That's 4 + 3 = 7 total triangles
Answer:
y = 5/7 x -5
Step-by-step explanation:
X/7- y/5=1
Multiply each side by 35 to clear the fractions
35(X/7- y/5) =1*35
5x - 7y = 35
Subtract 5x from each side
5x-5x-7y = -5x+35
-7y = -5x+35
Divide each side by -7
-7y/-7 = -5x/-7 +35/-7
y = 5/7 x -5
If human development really does proceed continuously, what value does stage theories of development have?
Answer:
Even if human development is continuous, there is some value in stage theories of development. A stage theory of development allows experts to examine the developmental progress of individuals and establish a basis for developmental changes. This can help identify developmental issues earlier. Stage theories can also help researchers who are examining physical development examine discrete changes in the brain that allow certain developmental milestones to be reached. Finally, stage theories can give one a sense of where an individual is developmentally, and can prepare the person for changes that may occur during their lifetime.
