Solve √(3x+7)+2√(x-8)=0.
laiz [17]

Answer:

The solution to this question is 39

Step-by-step explanation:

Given that :

√(3x+7)+2√(x-8)=0.    

√(3x+7)=-2√(x-8)           (i)

square of the equation (i)

Then

(√(3x+7))^2=(-2√(x-8))^2

we know that √a*√a=(√a)^2=a So,

(3x+7)=4(x-8)      

3x+7=4x-32        //multiply by 4

32+7=4x-3x  exchange the value.

39=1x

x=39.

Are the following expressions equivalent? Why or why not? <br> 6(2x + 4) and 12x + 24
MrMuchimi

Answer: Yes

Step-by-step explanation:

When using the distributive property, 6(2x + 4) becomes 12x + 24

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 12x + 24

Therefore, the expressions are equivalent.

The length of a rectangle is 4 more than 3 times the width if the perimeter of the rectangle is 18.4 cm what is the area of the
garik1379 [7]
Let's call the width: w

the lenght is then 3w+4 ("4 more than 3 times the width")

and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.

this is also equal to 18.4:

8w+8=18.4
8w=10.4
w=1.3

this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9

and the area is their product:
1.3*7.9=10.27

Which graph shows the points (−112, 12) and (1.5, −0.5) plotted correctly? On a coordinate plane, a point is 0.5 units to the ri
chubhunter [2.5K]

Answer:

Graph 'B' represents the correct graph.

The correct graph is attached below.

Step-by-step explanation:

Let 'A' be the point:

  • A\left(-1\frac{1}{2},\:\frac{1}{2}\right)

Let 'B' be the point:

  • B\:\left(1.5,\:-0.5\right)

As point A(-1 1/2, 1/2) can be written as:

A=\left(-\frac{3}{2},\:\frac{1}{2}\right)=\left(-1.5,\:0.5\right)

so plotting the point A=\left(-1.5,\:0.5\right)\:\:\:\: and B\:\left(1.5,\:-0.5\right) on a B\:\left(1.5,\:-0.5\right).

  • As we know that the 2nd quadrant, in the upper left-hand corner, consists of negative values of x and positive values of y.

Thus, the point A(-1.5, 0.5) will be plotted in the 2nd quadrant at x = -1.5 and y=0.5

i.e. at x= -1.5, y = 0.5

  • As we know that the 4th quadrant, the lower left-hand corner, consists of positive values of x and negative values of y.

Point B(1.5, -0.5) will be plotted in the 4th quadrant at x = 1.5 and y = -0.5

i.e. at x= 1.5, y = -0.5

Thus, graph 'B' represents the correct graph.

The correct graph is attached below.
