Find the square. (6m+7)2

Answers

Answer:

the square of  (6m+7)^2 is, 36m^2+84m+49

Step-by-step explanation:

To find the square of  (6m+7)^2

Using the identity:

(a+b)^2 = a^2+2ab+b^2

Apply this identity on the given expression:

(6m+7)^2

⇒(6m)^2+2(6m)(7)+7^2

Simplify:

⇒36m^2+84m+49

Therefore, the square of  (6m+7)^2 is, 36m^2+84m+49
( 6 m + 7 )² =

Apply distritutive rules:

(6m)² + 2 * 6 m * 7 + 7² =

6 m * 6 m + 2 * 6 m * 7 + 7*7 = 

36 m² + 84m + 49 

hope this helps!

A 15 foot ladder is leaning against a wall. The foot of the ladder is 7 feet from the wall. How high up the wall is the ladder? Round to the nearest tenth if necessary.

Answers

Answer:

13.26

Step-by-step explanation:

The computation of the height should be computed by using the Pythagoras theorem

As we know that

Hypothenuse^2 = base^2 + height^2

where,

Hypothenuse is 15 foot

And, the foot of the ladder i.e base is 7

So now placing these values

The height is

15^2 = 7^2 + height^2

225= 49 + height^2

After solving this, the height is 13.26

Abcd is a parallelogram. if m angle dab=115 then what does m angle bcd equal

Answers

I drew a picture, and unfortunately there isn't a way to upload it, so I'll just have to explain it to you.
DAB and BCD are opposite angles on a parallelogram, which makes that they are alternate interior angles when looking at it from a perspective of 2 parallel intersected lines. This means that DAB will have the same value as BCD, therefore BCD = 115 degrees
