See below in exact form
or
2.42, -12.42 to the nearest hundredth.
Step-by-step explanation:
x^2 + 10x - 13 = 17
(x + 5)^2 - 25 - 13 = 17
(x + 5)^2 = 17 + 38 = 55
x + 5 = +/- √55
x = -5 + √55, -5 - √55.

Answer:
<u>$3.90</u> was the cost of salami per kilogram.
Step-by-step explanation:
<u><em>The question is incomplete, so the complete question is below:</em></u>

Now, to find the cost of salami per kilogram.
Cost of
kilogram of sliced salami = $13.
Now, to get the cost of salami per kilogram we use unitary method:
If, the cost of
kilogram of salami = $13.
Then, the cost of 1 kilogram of salami =



Therefore, $3.90 was the cost of salami per kilogram.
Answer:
step 3: place the tip of the compass at point x and strike the arc at point y
Step-by-step explanation:
congruent triangles are triangles that have equal shape and size. They are the same in every way. this is the reason why they are called CONGRUENT
we have been asked to construct an angle MNT congruent to angle PQR. this means we are to construct angle that is the same as that at PQR.
with a ruler and a compass we can easily make a replica of the angle at PQR.
following the steps given in the question including step 3 that i have just added, the angle MNT will be the same as the angle PQR
If k is the scale factor between the dimensions of the similar solids, the areas are related by k² and the volumes are related by k³. That is


The areas are related by k², so



The ratio of the surface area of solid A to that of solid B is ...
