Answer:

Step-by-step explanation:Let a be the length of line

from question we know that

a+3 is another line

Here

a+(a+3)=15. ( Given in question )

2a = 15 -3

2a=12

a=12/2

a=6

To the nearest tenth, what is the square root of 89?
Bogdan [553]

Answer:

9.4.

Step-by-step explanation:

9^2 = 81 and 10^2 = 100

So the value of the square root of 89 is between 9 and 10.

The gap between the squares is 100-81 = 19 and the gap between 89 and 81 is 8 so an estimate of the square root would be 9 + 8/19  of the gap between 9 and 10.

9 + 8/19 = 8.42.

Kisachek [45]

Answer:

The vertex is ( -5,0)

Step-by-step explanation:

The vertex form of a parabola is

y = a( x-h) ^2 +k

where ( h,k) is the vertex

y=2(x+5)^2

y=2(x - -5)^2 +0

The vertex is ( -5,0)

pochemuha

Answer:

=x2y−2xy2+7y2z

Step-by-step explanation:

Simplify

Let's simplify step-by-step.

4x2y+3y2z−2xy2−3x2y+4y2z

=4x2y+3y2z+−2xy2+−3x2y+4y2z

Combine Like Terms:

=4x2y+3y2z+−2xy2+−3x2y+4y2z

=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)

=x2y+−2xy2+7y2z

Answer:

=x2y−2xy2+7y2z

Please help! i was wondering how you would solve this question!
Anon25 [30]

Answer:  C.  150 km²

<u>Step-by-step explanation:</u>

Use similar triangle proportion to find x:

\dfrac{x}{4.5}=\dfrac{15.3+7.4}{7.4}\\\\\\x=\dfrac{4.5(22.7)}{7.4}\\\\\\x=13.8\\\\\text{Notice that x is the diameter of the circle}\implies r=\dfrac{13.8}{2}=6.9\\\\\\\text{Find the area of the circle using }A=\pi r^2\\A=\pi (6.9)^2\\\\.\ =\pi (47.6)\\\\.\ =149.6\\\\.\ \approx150
