Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w(2w + 10) = 1500.

Simplify.

2w squared +10w = 1500

Make it a quadratic equation, w = 25 or -30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60
Width = 25

Help solve for x. round to the nearest tenth​
Llana [10]

Answer:

x = 3.7

Step-by-step explanation:

Apply trigonometric function to find x

Reference angle = 24°

Opposite = x

Hypotenuse = 9

This, apply SOH:

Sin 24 = Opp/Hyp

Sin 24 = x/9

9 × Sin 24 = x

3.66062979 = x

x = 3.7 (nearest tenth)

In AEFG, F = 61 inches, ZF=79º and ZG=34°. Find the length of g, to the nearest<br> 10th of an inch.
DENIUS [597]

Answer:

  g ≈ 34.7 in

Step-by-step explanation:

The law of sines is useful for this:

  f/sin(F) = g/sin(G)

Multiplying by sin(G), we have ...

  g = f·sin(G)/sin(F) = (61 in)·sin(34°)/sin(79°)

  g ≈ 34.7 in

What is 3(x+2)-10=4x-6+x <br>​
Natalija [7]

Answer:

1=x or x=1

Step-by-step explanation:

3(x+2)-10=4x-6+x

distribute

3x+6-10=4x-6+x

combine like terms

3x-4=5x-6

subtract 3x from each side

-4=2x-6

add 6 to both sides

2=2x

divide by 2
