Which of the following is equivalent to 7(x-5)+2(6-x)=12?

photoshop1234 [79]

Answer:

7x - 35 + 12 - 2x = 12

Step-by-step explanation:

Distribution is the first step. Multiply 7 to x and -35. And multiply 2 to 6 and -x. That gives you the answer 7x - 35 + 12 - 2x = 12.

Steve's bedroom measures 12 feet by 13 feet. Ricardo's bedroom measures 8 feet by 14

lina2011 [118]

Answer: Steve's bedroom has the greater area.

Step-by-step explanation: The formula for area is Area = Length x Width.

So all you have to do to figure this out is multiply the Width of the rooms by the length.

So Steve's room is 12ft X 13ft = 156ft

Ricardo's room is 8ft X 14ft = 112ft

156ft > 112ft

Steve's room has a greater area.

Which sequence is a geometric progression? A 2 4 6 8 B 1 1 2 3 С 1 2 4 8 D 1 3 5 7

Mars2501 [29]

Answer:

c) 1 2 4 8

Step-by-step explanation:

Explanation :-

Geometric sequence

The sequence is of the form a , a r , a r² , a r³ ,.......

'a' is the first term

'r' is the common ratio

1 , 1(2) , 1( 2)² , 1( 2 )³ ...... is a geometric sequence

here a = 1

common ratio $r = \frac{a_{2} }{a_{1} } = \frac{2}{1} = 2$

$r = \frac{4}{2} = 2$

$r = \frac{8}{4} = 2$

The sequence 1 2 4 8 is a geometric sequence
