Answer:

Step-by-step explanation:

0 + 1 = 1

1 + 2 = 3

3 + 3 = 6

6 + 4 = 10

10 + 5 = 15

15 + 6 = 21

Each number is added to an increase of 1 - first add 1, then add 2, then add 3,etc

Not listed but next would be 21 + 7 = 28

so it would be 0, 1, 3, 6, 10, 15, 21, 28

If h(x) = x – 7 and g(x) = x2, which expression is equivalent to(g*h)(5)? a (5 – 7)2, b (5)2 – 7, c (5)2(5 – 7), d (5 – 7)x2

asambeis [7]

H(x) = x - 7
g(x) = x^2
(g * h)(x) = x^2 (x - 7)
(g * h)(5) = 5^2 (5 - 7)

Find the perimeter for a square if one side measures: 4.5 cm

Alex17521 [72]

Answer:

18 cm.

Step-by-step explanation:

There are four sides on a square, and each side has the same measure as the other three. So, if one side measures 4.5 cm, four sides would be 4 * 4.5 = 4.5 + 4.5 + 4.5 + 4.5 = 9 + 9 = 18 cm

Hope this helps!

Question 2 (5 points) Saved

ratelena [41]

Answer:

(1, -1/2)

Step-by-step explanation:

7x - 2y = 8

5x + 2y = 4

I would use elimination to get rid of y

Add the two equations together

7x - 2y = 8

5x + 2y = 4

-------------------------

12x = 12

Divide each side by 12

x =1

Now find y

5x+2y = 4

5*1 +2y =4

Subtract 5 from each side

5+2y -5 = 4-5

2y = -1

Divide by 2

2y/2 =-1/2

y = -1/2
