Answer:

The base x is 14 centimeters ⇒ 1st answer

Step-by-step explanation:

The formula of the area of a triangle is A = \frac{1}{2} b h, where

  • b is the length of the base of the triangle
  • h is the length of the height of this base

In triangle ABC

∵ BC is its base

∵ AD is the height of base BC

∵ BC = x centimeters

∴ b = x

∵ AD = 7 centimeters

∴ h = 7

∵ The area of triangle ABC is 49 square centimeters

∴ A = 49

Use the formula of the area to find x

∵ A = \frac{1}{2} b h

∴ 49 = \frac{1}{2} (x)(7)

- Multiply both sides by 2

∴ 98 = 7 x

- Divide both sides by 7

∴ 14 = x

∴ The base x is 14 centimeters

HELP ME PLEASEEEE<br> I only know how to do this in division, not multiplication
Kipish [7]

Answer:

360 × 30

= (360 × 3) × 10

= 1080 × 10

= 10800

Step-by-step explanation:

For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.

1, 30

2, 15

3, 10

5, 6

So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.

Lets put 3 in the first blank and 10 in the second blank. We will end up with:

(360 × 3) × 10

Now 360 × 3 would be 1080. So the second line would be:

1080 × 10

1080 × 10 would equal 10800. So the final line and the final blank would be:

10800

So in order, the lines would be:

= (360 × 3) × 10

= 1080 × 10

= 10800

I hope you find my answer and explanation to be helpful. Happy studying.
