Answer: (B) No values of x make the equation true


7 = 2 is *not* true
There are no solutions to the equations

In other words, you cannot replace x with a value and get a true answer

No values of x make this equation true

Hey. Let me help you on this one.

In order for us to solve this question, we need to break this problem apart. It will make it easier to understand.

In this problem, we see five different figures - four triangles, and one square.

If we want to get the complete net-surface area, we will need to find area of each figure individually, and then, add all values together.

Let's start with a square in the center. Formula for area of a square is S=a*a. In this formula, S stands for total area of a square, and  stands for the length of one side.

Let's substitute the values!
S=4*4
S=14

Area of the square is 14 inches squared. Awesome! Now, let's find the area of all triangles.

We can see that one of the triangles has both measures - base, and the height. We need these two values in order for us to find the measure of the triangles.

Formula for the area of a triangle is S= \frac{a*b}{2}. So, we need to multiply base length by the height length, and divide by two.

S= \frac{4*8}{2}
S= \frac{32}{2}
S=16

Now, we know the area of one triangle. We have three other identical triangles, and in order for us to save time, let's just multiply this number by four. 
16*4=64

Triangles are 64 inches squared in total.
64 inches squared + 14 inches squared (square area) equals to 78 inches squared.
Answer: 78^{2} is the area of the figure

Margaret is dividing 829 by 4. Explain why Margaret needs to write a zero in the tens place of the quotient
aliina [53]
Quotient is the number gotten when you divide a number by a diviser.
In this case our number is 829 and the diviser is 4, and the quotient is 207.25. When the first digit 8 is divided by 4, we get 2, then since the second digit 2 is less than four we must put zero on the tens digit of the quotient so that we can pick the third digit 9 to form 29 which is greater than 4,and the process continues ...

Consider the following system:
mr Goodwill [35]

Answer:

The systems of equation are identical and such there are infinitely many solutions. For the first part the correct answer is B. For the second part, the correct answer is A

Step-by-step explanation:

If we multiply the first equation by 4 the result is the second equation and thus the systems of equations are scalar multiples of each other. The solution to such a system is found by expressing one variable in terms of the other hence choice B.

Since the systems are scalar multiples of each other, if we graph them they would simply coincide since they are identical, that is they have same slope and y-intercept.
