Can someone help me on this

Mathematics
1 answer:
SCORPION-xisa [38]3 years ago
5 0

Step-by-step explanation:

(a) n² + 3

First term = 1² + 3 = 4

Second term = 2² + 3 = 7

Third term = 3² + 3 = 12

Fourth term = 4² + 3 = 19

10th term = 10² + 3 = 103

(b) 2n²

First term = 2(1)² = 2

Second term = 2(2)² = 8

Third term = 2(3)² = 18

Fourth term = 2(4)²= 32

10th term = 2(10)² = 200

Hence, this is the required solution.

PLEASE HELP! which answer is correct??
Solnce55 [7]
Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.

Verdich [7]

Answer:

b = $4000

Step-by-step explanation:

Let b represent the bonus amount.

Then the bonus, b, less the three deductions, is represented by

b - 0.30b - 0.30b - 025b, and this comes to $600.  Find the value of b.

b - 0.85b = $600, or

0.15b = $600

Then b = $4000

Sections of prefabricated fencing are each 4 1/3 feet long. how long are 6 1/2 sections placed end to end
zalisa [80]

we know that

4\frac{1}{3}= \frac{(4*3+1)}{3} =\frac{13}{3}

6\frac{1}{2}= \frac{(6*2+1)}{2}=\frac{13}{2}

To find how long are 6\frac{1}{2}  sections placed end to end

Multiply the number of sections by the length of one section

so

\frac{13}{2} *\frac{13}{3} =\frac{169}{6}\ ft

\frac{169}{6}\ ft =28\frac{1}{6}\ ft

therefore

<u>the answer is</u>

28\frac{1}{6} \ ft
