Step-by-step explanation:
area ofQXRY = area of PQRS- area of PXYS
= 84 - 21
area of QXRY = 63 cm²
Now
In
QXRY
area of rectangle = l×b
= 9cm × a
or, 63 =9a
so, a = 7 cm
Now
for PXYS
Area of rectangle = l×b
21 = a×b
because QR = PS = a cm (opposite sides of rectanhle are equal)
or, 21=7b
so, b = 3cm
so,
a= 7cm
b= 3cm
Answer:
b=22
Step-by-step explanation:
1 Remove parentheses.
b-11-29=-18b−11−29=−18
2 Simplify b-11-29b−11−29 to b-40b−40.
b-40=-18b−40=−18
3 Add 4040 to both sides.
b=-18+40b=−18+40
4 Simplify -18+40−18+40 to 2222.
b=22b=22
Answer:
if x=6 then y=-55
Step-by-step explanation:
because 41-27 is 14 so u need to subtract 14 from -41 to get ur answer
