<u>Answer:</u>
<h3>(
) x (
) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
( ) x ( )
The area = 
So, the equation to find the area of such a rectangle would be:-
( ) x ( )
Answer:
Step-by-step explanation:
Take out 3x from both sides:
5x - 3x = 3x - 3x
2x = 0
2x + 9 = 1
Take out 9 from both sides:
9 - 9 = 1 - 9
0 = -8
Divide 2 from both sides:
Step-by-step explanation:
Number of students who wore a hat
= 4/7 * Number of students who bought a ticket
= 4/7 * 350 students
= 200 students.
Number of students not wearing a hat
= Number of students who bought a ticket - Number of students who wore a hat
= 350 students - 200 students
= 150 students.
Answer:
4
Step-by-step explanation:
Answer:
A. The next 3 terms are —9, —11, —13
B. The sequence is Arithmetic
C. The sequence has a common difference of —2
Common difference = T2 — T1 or = T3 — T2
=T2 — T1 = —3 —(—1) = —2 or
= T3 — T2 = —5 —(—3) = —2
D. Tn = a + d(n—1)
a = first term = —1
d = Common difference = —2
n = 27
T27 = —1 + —2(27—1)
T27 = —1 + —2(26)
T27 = —1 —52
T27 = —53
