Hello, thanks for using Brainly!
We are solving 6x6-4+9.
We will do three steps in this case.
First is 6x6, 6x6 is 30.
So now we must keep in our head we have 30 as our first number.
Now, let's -4 from 30. 30-4 is 26.
We just did step 2. Boom!
So, we have 26 as our second number. Let's do our third step.
If we have 26, we need to add 9 to that. To quickly find that we know that 26+10 is 36. That is adding ten, we need 9 so minus 1 from 36 we get 35.
Our final answer is 35.
Answer:

A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.
W + d = 770
w = d + 70
d + 70 + d = 770
2d + 70 = 770
2d = 770 - 70
2d = 700
d = 700/2
d = 350 <=== cost of dryer
Answer:
B)15 yards
Step-by-step explanation:
We can solve this using Pythagoras theorem as
Let
Width of the pool= c
Length of diagonal of swimming pool =b
Length of the pool= a
c^2= b^2 + a^2
c^2 - b^2 = a^2
C^2 = 29^2 - 25^2
C^2=( 841-625)
C= √216
( Width of the pool)=15 yards
Hence, measurement is closest to the width of the pool is 15 yards
