So try to isolate a by division and such
K=4a+9ab
we use reverse dstributive which is ab+ac=a(b+c) so
undistribute a
4a+9ab=a(4+9b)
k=a(4+9b)
divide both sides by (4+9b)

=a
a=
Answer:
do 8 times 4.2 then subtract the .6 to get to 33 hope this helped

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that <u>tangents </u><u>which</u><u> </u><u>meet </u><u>at</u><u> the</u><u> </u><u>same</u><u> </u><u>point</u><u> </u><u>are </u><u>equal</u><u> </u><u> </u>that is being said
since
and it's given that FA and BA are 17 and 29 FB should be
therefore,
once again by two tangent theorem we acquire:
As BC=BH+CH,BC is
- 12+2.5

likewise,AD=AI+DI so,
- 21=17+DI [AD=21(given) and AI=17 (by the theorem)]
thus,
- DI=21-17=

By the theorem we obtain:
Similarly,DC=DG+CH therefore,
- DC=4+2.5=

Now <u>finding</u><u> </u><u>the</u><u> </u><u>Perimeter</u><u> </u><u>of </u><u>ABCD</u>
substitute what we have and got
simplify addition:
hence,
the Perimeter of ABCD is <u>7</u><u>1</u>
Answer:
y = -
x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
and c = - 4 , thus
y = -
x - 4 ← equation of line
