Answer:
Choice B & C
Step-by-step explanation:
563 - 192 = 371
The subtraction equals to 371.
100 + 90 + 210 = 400
The answer does not equal to 371 in choice A.
563 - 200 + 8 = 371
The answer equals to 371 in choice B.
571 - 200 = 371.
The answer equals to 371 in choice C.
Answer:
1st graph is Y=1x+0
2nd Graph is Y=-2/1x + 0
Step-by-step explanation:
Your slope is 1 for the 1st graph
Your slope is -2/1 for the second graph
Five times the sum of x and negative two, or five times the difference of x and two
Answer:
16x² +48x +36
Step-by-step explanation:
A perfect square trinomial is of the form ...
(a +b)² = a² +2ab +b²
We want to match this form.
__
<h3>comparing terms</h3>
Comparing the known terms, we see ...
16x² = a² ⇒ a = 4x
36 = b² ⇒ b = 6
<h3>filling in the missing term</h3>
The missing term is the linear term:
2ab = 2(4x)(6) = 48x
? = 48
Answer:
41 years old.
Step-by-step explanation:
Let x represent age of younger child.
We have been given that a mother has two children whose ages differ by 5 years. So the age of older child would be
.
The sum of the squares of their ages is 97. We can represent this information in an equation as:

Let us solve for x.



Divide both sides by 2:






Since age cannot be negative, therefore, age of younger child is 4 years.
Age of older child would be 
Therefore, the age of older child would be 9 years.
We have been given that the square of the mother's age can be found by writing the squares of the children's ages one after the other as a four-digit number.
Square of 4: 
Square of 9:
.
Square of mother's age: 
To find mother's age, we need to take positive square root of 1681 as:

Therefore, the mother is 41 years old.
