3 is incorrect, should be 28.9

16^2 + 18^2 = EG^2
256 + 324
580 = EG^2
EG ≈ 24.08

16^2 + 24.08^2 = AG^2
256 + 580 = AG^2
836 = AG^2
AG ≈ 28.9

5 is incorrect:

The base is 8.
Draw an altitude the base.
Since the triangle is isoceles, it divides the base in half.
Half of that base is 4.
Two right triangles have been formed with one leg 4 and hypotenuse 8.
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b ≈ 6.93

The height of the triangle is 6.93, the base is 8.
A = bh/2 = 8*6.93/2 ≈ 27.7 ≈ 28

Please help Cant figure it out

IrinaVladis [17]

Answer:

C

Step-by-step explanation:

If a number is to the power of a negative number, then it is just that number's reciprocal: e.g. y⁻ˣ = $\frac{1}{y^{x} }$

Therefore, m⁻² will be m² in the denominator, as n⁻³ will be n³ in the numerator.

That will look like $\frac{3n^{3} }{5m^{2} }$ .

So, that is C.

For questions 2 z 3. simplify each polynomial <br>2. 3x²+6-2x+5x-4x²+9<br>3. 2x²+6x-7x+8-3x²+1

Mars2501 [29]

Answer:

2. $-x^{2} +3x+15$

3. $-x^{2} -x+9$

Step-by-step explanation:

We add like terms together to simplify

2. 3x²-4x²= -x² -2x+5x= 3x 6+9= 15 all equal to -x²+3x+15

3. 2x²-3x²= -x² 6x-7x= -x 8+1=9 all equal to -x²-x+9

If it is 76 feet LOWER than 73 above sea level, then you must do
73-76= -3
So Mudville is 3 feet BELOW sea level.
