Answer:

840cm²

Step-by-step explanation:

The two small triangle areas:

b × h / 2 = 12 × 5 = 60 / 2 = 30cm²

So two triangles would be 60cm²

Now, for the top rectangle:

b × h = 26 × 12 = 312cm²

The middle rectangle:

b × h = 26 × 13 = 338cm²

And the bottom last triangle:

b × h = 26 × 5 = 130cm².

Now to add them all: 60 + 312 + 338 + 130 = 840cm²

I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)

0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180

The answer is B.

When u=-2, put that in where you see "u". use parentheses.
-4(-2)+4x=12

-4*-2=8 ➡positive 8 since a negative times a negative is always positive

now look for x
8+4x=12
subtract 8 from both sides. get x by itself.

-8+8+4x=12-8
4x=4➡ divide both sides by 4. a number divided by itself is 1 (unless one side is negative, then the answer is negative)
4/4=1

x=1

If AB = 9 and BC = 12 then what is AC?
dimaraw [331]

Answer:

AC = 12 cm

Step-by-step explanation:

AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.
