37-(-3)squared+30\(-3)x2
vampirchik [111]
Simplify: 
37 - (-3)^2  + 30/(-3)x^2
= 37 +  - 9 +  - 10x^2

Combine like terms:
= 37 +  - 9 +  - 10x^2
= ( - 10x^2) + (37 +   - 90
= - 10X^2 + 28
Answer: - 10x^2  +  28



To Factor: 
37 - (- 3)^2 + 30/- 3x^2

- 10x^2 + 28
- 2(5x^2 - 14)

Answer:  - 2(5x^2 - 14)




I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -





Hope that helps!!!!

A power lifter is leg-pressing 720 pounds on a leg press machine. The angle of the press is 60 degrees. What is the actual weigh
Triss [41]

Since, the angle between the machine and angle of press is 60^{\circ} as shown in the attached image.

Therefore, the actual weight lifted by the power lifter is given by w \times \cos \Theta

where 'w' stands for the weight being lifted and \Theta is the angle of press.

Now,

actual weight lifted by the power lifter = 720 \times \cos 60^{\circ}

= 720 \times \frac{1}{2} = 360 pounds.

How to solve a pair of equations
IgorC [24]
I assume what you mean by this question is an equation like this:

1 + 2 x 3 + 4
Or,
3 x 4 + 6 /div 5

What you'd do:
1+2 x 3+4 First, add either 1+2 or 3+4 which is 3 & 7. then, youd multiply your answers as, 3 x 7 which is, 21.

The length of a rectangle is 5 more than twice the width. If the perimeter of the
Rzqust [24]

Answer:

The dimensions of the rectangle are two unknowns: The length "l" and the width "w"

The perimeter of a rectangle is found as P = 2*l + 2*w

We also know that the length is 5cm more than twice the width. l = 2*w + 5

These two equations gives us a system of linear equations.

P = 2*l + 2*w

l = 2*w + 5

We can use substitution to replace the "l" in the first equation with 2*w + 5

P = 2*(2*w + 5) + 2*w

P = 4*w + 10 + 2*w

P = 6*w + 10

We know that P = 34cm

34 = 6*w + 10

Subtract 10 from both sides

24 = 6 * w

Divide both sides by 6

4 = w

Now that we know the width, we can find the length by substituting 4 for "w" in the second equation.

l = 2*4 + 5

l = 8 + 5

l = 13

The dimensions of the rectangle is 13cm x 4cm
