gotchu
i had to edit it on my laptop with the marker tool so be nice ik the handwriting suckssss
i'll write the points for you here tho:
(-2,-12)
(-1,-6)
(0,-3)
(1,-1.5)
Answer:
QR = 48 units
Step-by-step explanation:
in a rectangle, opposite sides are equal
so QR = PS and QP = RS
also we know that the sum of all sides is the perimeter, which is 176
we can set up this equation:
2(5z - 2) + 2(4z) = 176
10z - 4 + 8z = 176
18z - 4 = 176
18z = 180
z = 10
QR = 5z - 2
we can substitute 10 for 'z' to get:
5(10) - 2 = 50 - 2 or 48
Check:
2(48) + 2(40) = 176
96 + 80 = 176
176 = 176
Answer:
x = 4 or x = -10 for equation x^2 + 6x = 40
Step-by-step explanation:
x^2 + 6 = 40
x^2 = 40 - 6
x^2 = 34
x = root(34) or x = -root(34) but this is not in the answer choice.
is it x^2 + 6x = 40
x^2 + 6x + 9 = 40 +9
(x + 3)^2 = 49
x + 3 = 7 or x + 3 = -7
x = 4 or x = -10
Hello!
Use the following formula for the perimeter:
P = 2l + 2w, where:
l = length
w = width
Therefore:
P = 2(90) + 2(60)
Simplify:
P = 180 + 120 = 300 m
