i think i em right but not sure hope it right
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: D
Step-by-step explanation:
The expression for x-value of the vertex is (-b/2a). Doing this will give you the time of 3.8125 seconds.
