The perimeters of the triangles shown are equal.Find the side length of each triangle.
3x+8 AB=
3x+7 BC=
3x AC=
3x PQ=
3x QR=
4x+2 PR=

Answers

i’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132

Two friends, Sasha and Maria, are growing out their hair. They plan to cut it off at a certain
point and donate it to a charity that makes wigs for people with cancer. Sasha's hair is
already 10 centimeters long and grows at a constant rate of 3 centimeters per month. Maria's
hair is 36 centimeters and growing at a speed of 1 centimeter per month. If the girls get their
hair cut on a certain day, they will have exactly the same length to donate. How long will that
take? How long will their hair be?
In
months, both girls' hair will be
centimeters long,

Answers

Answer:

13 months, 49 cms

Explanation:

For Sasha, multiply 3 and 13 together for the growth per month. You should get 39, then add the 10 cm Sasha already has. The sum is 49.

For Maria, multiply 13 and 1 for the growth per month. You should get 13, then add the 36 Maria already has. The sum is also 49.

It takes 3 people a total of 192 hours to build a wall. How long would it take if 12 people built the same wall?

Answers

you need to solve this using fractions.

Example :

It takes 3 men 8 hours to build a wall. How long would it take 4 men to build the same wall?

For 1 man: It is 1/8 divided by 3, which is 1/24.

For 4 men: It is 1/24 multiplied by 4, which is 1/6, = 6 hours.

Answer:

They are not congruent because they are not facing the same way.

Step-by-step explanation:

SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

That is which postulate proves congruency.

Answer:

They are not congruent would be my guess cause the sides are not the same my bad if it is wrong lil br uh

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object.

A goalie makes 12 saves in 4 games. What is the unit rate of saves per​ game?

Answers

Answer:

3 saves per day

Step-by-step explanation:

Since we are finding the number of saves per day, our first dividor will be the number of saves, then we divide by the other number. We have 12 saves in total, and four games, so we will have to divide.

12 divided by 4 is equal to 3.

The answer to the question must be 3.

Answer:

12 saves/ 4 games = 3 saves/ 1 game = 3 saves per game

Step-by-step explanation:

A ration is basically a division problem. Divide until you get a denominator of 1.

12/ 4 = 3/ 1

So, if he makes 12 saves in 4 games, then he makes 3 saves per game.

What are the zeros of the polynomial function? State the multiplicity of each zero y=(x+2)(x-3)^2

Answers

Answ er:

-2,  3

Step-b y-step explanation:

The question is asking what x equals that makes y equals 0

How do we do this?

Because we're multiplying things together we just need one part of the equation to equal 0

for example if x= -2 then we would have the following

(-2+2)(-2-3)^2

(0)(-5)^2

which is 0

and the other answer is 3 because when you have

x-3=0

x= 3
