The perimeter of a rectangle must be less than 156 feet. If the length is known to be 66 feet, find the range of possible widths
balu736 [363]

x = perimeter

x<156

length = 66

so, in order to calculate perimeter you need to add two lengths and two widths

so

156 (perimeter) - 2 (66) = two widths

156 - 132 = 24 (remember this number is two widths added together)

so 24 twice the width SO 12 would be the number that the width can't be larger than

the width has to be less than 12

w < 12

PLZZZ HELP ME!!!!! <br><br>Complete the table for the function f(x) = 2x - 3
Lana71 [14]

Answer:


Step-by-step explanation:

f(x) = 2x - 3

f(-2) = 2(-2) -3 = -4 - 3 = -7

f(-1) = 2(-1) -3 = -2 - 3 = - 5

f(0) = 2(0) -3 = 0 - 3 = -3

f(1) = 2(1) -3 = 2 - 3 = -1

f(2) = 2(2) -3 = 4 - 3 = 1

f(3) = 2(3) -3 = 6 - 3 = 3

find three consecutive even integers so that the twice the sum of the second and third is twelve less than six times the first
zysi [14]

n, n + 2, n + 4 - three consecutive even integers

the twice the sum of the second and third: 2[(n + 2) + (n + 4)]

twelve less than six times the first: 6n - 12

The equation:

2[(n + 2) + (n + 4)] = 6n - 12

2(n + 2 + n + 4) = 6n - 12

2(2n + 6) = 6n - 12       <em>use distributive property</em>

(2)(2n) + (2)(6) = 6n - 12

4n + 12 = 6n - 12       <em>subtract 12 from both sides</em>

4n = 6n - 24       <em>subtract 6n from both sides</em>

-2n = -24        <em>divide both sides by (-2)</em>

n = 12

n + 2 = 12 + 2 = 14

n + 4 = 12 + 4 = 16

<h3>Answer: 12, 14, 16</h3>
