First solve the length of side BC, CD, EF and FA
Since BC = CD = sqrt( 10^2 + 10^2)
BC = CD = 14.1421
FA = EF = sqrt(10^2 + 20^2)
= 23.3607
So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607
= 93
The area is made up be triangle FAE, rectangle ABDE and
triangle BCD
A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)

Answer:
y=5x is not linear
Step-by-step explanation:
option A is not linear
Answer:
A, C, D
Step-by-step explanation:
Remember: Exponents are simply repeated multiplication.
The exponent determines how many times to multiply the base number by itself.
Option 'A' and 'C' apply.
Option D applies because:
Answer:
-9
Step-by-step explanation:
Simplify the following:
7 - 8/4 (3^2 - 1)
Hint: | Evaluate 3^2.
3^2 = 9:
7 - 8/4 (9 - 1)
Hint: | Subtract 1 from 9.
9 - 1 = 8:
7 - 2×8
Hint: | Divide 8 by 4.
8/4 = (4×2)/4 = 2:
7 - 2×8
Hint: | Multiply -2 and 8 together.
-2×8 = -16:
7 + -16
Hint: | Subtract 16 from 7.
7 - 16 = -9:
Answer: -9
