NEEEEEEEEEEEEEEEEEEEDDDDDDDD HELP

Mathematics
1 answer:
Makovka662 [10]2 years ago
8 0

Answer:

Step-by-step explanation:

1.

19² = 17² +x²

19² - 17² = x²

√361-289 =x

√72 = 8.5 ≈ x

Area = base*h/2 = 17*8.5/2 ≈ 72.3

Perimeter = 19+17+8.5= 44.5

and so on...

2.

x²= 5² +13²...

A= 5*13/2 =...

P= 5+13+x=...

3.

20² = 10² +x²...

A=10*x/2=...

P=20+10+x=...

4.

x² = 5² +14²...

A=5*14/2 =...

P= 5+14+x = ...

M(x) = 4x + 15; m(x) = 7
stealth61 [152]

Hi there! :)

\huge\boxed{x = -2}

m(x) = 4x + 15

Find the value of "x" that would satisfy m(x) = 7:

4x + 15 = 7

Subtract 15 from both sides:

4x = -8

Divide both sides by 4:

x = -2.

Pls help ASAP need help pls
AlexFokin [52]

Answer:

1.625

Step-by-step explanation:

First we need to find the mean of this data set

29+32+33+28+30+30+29+33=244

Then we divide 244 by the amount of numbers in the set

244/8=30.5

Then we need to find the deviation of each number

29 | 32 | 33 | 28 | 30 | 30 | 29 | 33

1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5

Then we take the mean from this set of data

1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13

Then divide

13/8=1.625

I hope this helps :)
