Here's [10] if you don't beat me to it by the time I finish typing:

9t^2 +12t + 4 = (3t      blank)(3t       blank)
= (3t  + 2)(3t + 2)

CHECK:
3t*3t + 3t*2 + 2*3t + 2*2
= 9t^2 + 6t + 6t + 4
= 9t^2 + 12t + 4

ANSWER: (3t + 2)(3t + 2)

Find the value of x and y in the given parallelogram
frez [133]

Answer:

Step-by-step explanation:

9y-4 = 50

9y = 54

y= 6

9y-4+7x+xy = 180

9(6)-4+7x+6x= 180

54-4+13x = 180

13x+50 = 180

13x = 130

x = 10

find the value of the letter in each of the following and give reasons for the steps involved 1 2 A+6 A B=A 0 9​
nekit [7.7K]

Question:

Find the value of the letter in each of the following and give reasons for the steps involved:

1 2 A

+ 6 A B =

A 0 9

Answer:

128 + 681 =  809

Step-by-step explanation:

Here, let's use the general form of numbers where any  letter must represent one value and each digit must be represented by just one letter.

Take the following:

A = 8

B = 1

Thus, A +B = 8 + 1 = 9

Also add:

8 + 2 = 10

In general form, tens digit is zero and the 1 is carried over.

I.e, A = 1 + 6 + 1 = 8

We can now see that,

A = 8

B = 1

Therefore,

1 2 A

+ 6 A B =

A 0 9

Will be written as:

128 + 681 =  809
