Y=1/2x-2
Since y is 2 less than half of x, you subtract to from 1/2x to equal y.
Answer:
z^4-z²-20
Step-by-step explanation:
( z^2 + 4 ) ( z^2 – 5)
z^4+4z²-5z²-20
z^4-z²-20
Answer:
90 cm²
Step-by-step explanation:
The area of the shaded portion is the area of parallelogram ABCD minus the area of triangle EBC.
ABCD is a parallelogram with base 18 cm and height 10 cm.
A(parallelogram) = bh = (18 cm)(10 cm) = 180 cm²
EBC is a triangle with base 18 cm and height 10 cm.
A(triangle) = bh/2 = (18 cm)(10 cm)/2 = 180 cm²/2 = 90 cm²
shaded area = 180 cm² - 90 cm² = 90 cm²
Answer:
3.14
