The answer is -40
-2(12-2(-4))
-2(12+8)
-2x20
-2x20 = -40
0.65 multiplied by 75
The answer is 49%
All you do is distribute you multiply x x 4 then 5 times 4 and then you divide 20 by 4 then x equals 5
To get the percentage of area we shall proceed as follows:
linear scale factor =length of herb/ length of garden
=4/10
but
area scale factor=(linear scale factor)^2
area scale factor=(2/5)^2=4/25
thus the percentage area proportion will be:
4/25*100
=16%
Answer:
c
Step-by-step explanation:
Since the perimeters are equal, then equate the perimeter expressions, that is
4(x - 2) = 6(
x + 5) ← distribute parenthesis on both sides
4x - 8 = 3x + 30 ( subtract 3x from both sides )
x - 8 = 30 ( add 8 to both sides )
x = 38
Substitute x = 38 into either of the 2 perimeter expressions
perimeter = 4(x - 2) = 4(38 - 2) = 4 × 36 = 144 in → c
