Answer:x=31.4919
Step-by-step explanation:
Step1:isolate a square root on the left hand side√x+3=√2x-1-2
Step2:eliminate the radicals on the left hand side
Raise both sides to the second power
√x+3)^2=(√2x-1-2)^2
After squaring
x+3=2x-1+4-4-4√2x-1
Step3:get the remaining radicals by itself
x+3=2x-1+4-4√2x-1
Isolate radical on the left hand side
4√2x-1=-x-3+2x-1+4
4√2x-1=x
Step4:eliminate the radicals on the left hand side
Raise both side to the second power
(4√2x-1)^2=x^2
After squaring
32x-16=x^2
Step 5:solve the quadratic equation
x^2-32x-16
This equation has two real roots
x1=32+√960/2=31.4919
x2=32-√960/2=0.5081
Step6:check that the first solution is correct
Put in 31.4919 for x
√31.4919+3=√2•31.4919-1-2
√34.492=5.873
x=31.4919
Step7:check that the second solution is correct
√x+3=√2x-1-2
Put in 0.5081 for x
√0.5081+3=√2•0.5081-1-2
√3.508=-1.873
1.873#-1.873
One solution was found
x=31.4919
The first solution involves the volume of a pyramid. With the parameters, the volume is given as: 51cm³
<h3>What is the Volume of a Pyramid?</h3>
The volume of a pyramid is given as:
V = (lwh)/3
Where:
- L = base length
- w = base width
- h = pyramid height.
Hence, the volume of the pyramid is given as:
(6 x 5.2 x 4.9)/3
= 152.88/3
= 50.96
≈ 51 cm³
<h3>
What is the volume of the juice container?</h3>
Assuming that it is a cuboid, the volume for the shape of a cuboid is given as:
L x B x H
Where:
L = Length = 2cm
B (Width) = 34cm
H = Height = 12.2
Hence the Volume =
2 x 34 x 12.2
= 829.6
≈ 830 cm³
<h3>
What is the volume of the pit?</h3>
We are not given it's geometric description so we assume that it is a Cuboid.
Recall that the Volume of a Cuboid = L x B x H
Hence the Volume of the pit is:
7 x 5 x 8
<h3>
= 280 cm³
How much space can a box that measures 50cm on each edge hold?
</h3>
From the question, we can infer that we are dealing with a Cube.
The volume of a cube is given as L³.
Recall that L = 50cm
Hence, the volume is = 50³
= 125,000 cm³
<h3>
What is the volume of a rectangular prism?
</h3>
The formula for the volume of a rectangular prism is:
L x W x H; where
L (Length) = 130cm
W (Width) = 70cm
H (Height) = 110cm
→ 130 x 70 x 110
= 1,001,000 cm³

I would say you cannot use a rectangle. Or a circle. One of those.
Odd integers are 2 apart
they are
x,x+2,x+4
sum is -75
x+x+2+x+4=-75
3x+6=-75
minus 6 both sides
3x=-81
divide both sides by 3
x=-27
x+2=-25
x+4=-23
the largest is the farthest to right on a number line
largest is -23
