Answer:
90
Step-by-step explanation:
PVQ = 60 an RVS = 30, 60 + 30 = 90
We rewrite the expresion:
((t+3)/(t+4))*(1/(t^2+7t+12))
We have then
((t+3)/(t+4))*(1/((t+4)*(t+3)))
Rewriting tge expression:
(1/(t+4)^2)
Answer:
(1/(t+4)^2)
opcion 3
1,2,3,4,6,9,12,18,36
please can i have a brainliest
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
