Answer:
see explanation
Step-by-step explanation:
let w represent the width then length = w + 7
The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14
The perimeter is given as 54 m, thus
4w + 14 = 54 ( subtract 14 from both sides )
4w = 40 ( divide both sides by 4 )
w = 10
Thus
width of playground = w = 10 m
length of playground = w + 7 = 10 + 7 = 17 m
Answer:
0.25
Step-by-step explanation:
Givens
orange: 75
Blue: 62
Green: 52
Red: x
Total: 252
Equation
75 + 62 + 52 + x = 252 Collect the like terms on the left.
Solution
189 + x = 252 Subtract 189 from both sides
x = 252 - 189
x = 63 Red Ones
Probability
P(Red) = 63/252
P(Red) = 0.25
Answer:
y = -2/3x + 6
Step-by-step explanation:
Kind of hard to explain but...
From 0,0 go up 6, that is where the + 6 comes from in the answer
The -2/3 is because if you go down 2 (aka -2) and right 3 (aka 3) from point 0,6 you land on point 4,4
In my opinion the answer is <span>m2 – 100 = –99
proof
</span>m2 – 100 =<span>(m – 10)(m + 10)
for eg. m=1, </span>(-9)(11)= <span>–99</span>
