love history [14]3 years ago
6 0

Answer:

First box = 22.5, 45/2, or 22 and 1/2

Second box = square inches (because area is always ^2, or squared)

Step-by-step explanation:

A = B * H

B = base

H = height

Base = 5 inches

Height = 4.5 inches

5 inches * 4.5 inches = 22.5 inches^2

This can also be written as 45/2 or 22 and 1/2

I hope I helped!

Let me know if you need anything else!

Find the missing value<br> 8<br> 14<br> 45 <br> 15
alekssr [168]

Answer:

The correct option is B.

Step-by-step explanation:

From the given figure it is nices that the length of sides AB, BC and AC are 20, 22 and 35. The line AD is angle bisector.

Let the missing value be x.

The Triangle Angle Bisector Theorem states that the angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.

Since AD is angle bisector, therefore

\frac{AB}{AC}=\frac{BD}{CD}

\frac{20}{35}=\frac{22-x}{x}

20x=35(22-x)

20x=770-35x

Add 35x both sides.

55x=770

Divide both sides by 55.

x=\frac{770}{55}

x=14

Therefore, second option is correct.

Write the equation of the line that has the slope m=2/5 and passes through the point ​(25​,−9​). Write the equation in​ slope-in
klemol [59]
You're given the slope of the line and a point thru which the line passes.  So it makes sense to use the point-slope form of the equation of a straight line:  if the point is (a,b) and the slope is m, then 

y-b=m(x-a).  You'd then solve this for y to obtain the equation in slope-intercept form.

On the other hand, if you're asked to write the equation in slope-intercept form, starting with the general form of this equation may be faster:  y=mx+b.

Substitute the given values for x and y (which are 25 and -9) and m (which is (2/5).  Solve the resulting equation for b (the y-intercept).

Then write the finished equation:  y=( ? )x + b, where b is the y-intercept you've just found.
