Answer:i had a paper just like that and i’m pretty sure the answer is 170 for number 5
Step-by-step explanation:could be wrong
Answer:
y+7=
(x-1)
Step-by-step explanation:
slope of -2/3, so m=-2/3
point slope form=y-
=m(x-
)
plug in your slope as well as your x and y values from your point
y-(-7)=(-2/3)(x-1)
y+7=
(x-1)

Answer:
C. 12cm
Step-by-step explanation:
The equation for the perimeter of the rectangle is ...
P = 2(L+W)
34 = 2(n +m)
Solving for m, we get
m = 17 -n . . . . . . . divide by 2, subtract n
__
The Pythagorean theorem gives the relationship between the sides and the hypotenuse
m^2 +n^2 = (n+1)^2
(17 -n)^2 +n^2 = (n +1)^2 . . . . . . substitute for m
289 -34n +n^2 +n^2 = n^2 +2n +1 . . . . eliminate parentheses
n^2 -36n +288 = 0 . . . . . . . put in standard form
(n -12)(n -24) = 0 . . . . . . . . . factor
n = 12 . . . . . . . . . . n=24 is an extraneous solution here
The value of n is 12 cm.
Answer:
22
Step-by-step explanation:
First I add all of the numbers given and I get 40. Now 40 - 18= 22.
Here, you'd combine like terms.
2.5 + 3.4 = 5.9
10^4 + 10^4 = 10^8
5.9 x 10^8
