Answer:

X=15

Step-by-step explanation:

Yes, you are right.

The given equation is

X+U=25

If U=10, then we substitute to obtain:

X+10=25

Subtract 10 from both sides to get:

X=25-10

Simplify to get:

X=15

Solve for the given length. The length of a rectangle is 3m longer than its width. The area of the rectangle is 154^2. What is t

Andre45 [30]

If the length of a rectangle is 3m longer than its width, then:
L=W+3
Is the area really 154^2? Or is it 154m^2? If yes, then:
A=LW
154=(W+3)(W)
154=(W^2+3W)
0=W^2+3W-154
0=(W-11)(W+14)
This means either (W-11) or (W+14) is equal to zero so:
W=11 and W=-14
To find out let's substitute the numbers:
154=(11+3)(11)
154=154
Therefore, the width of the rectangle is 11m

Oksi-84 [34.3K]

Answer:

$9\sqrt{3}$ cm^2

Step-by-step explanation:

area of an equilateral triangle = $\frac{s^{2} \sqrt{3} }{4}$ (s = length of the side)

area = $\frac{6^{2}\sqrt{3} }{4}$

area = $\frac{36\sqrt{3} }{4}$

area = $9\sqrt{3}$ cm^2
