Steps to solve:

56 < 7(7 - x)

~Distributive Property

56 < (7*7) + (7*-x)

~Simplify

56 < 49 - 7x

~Subtract 49 to both sides

56 - 49 < 49 - 49 - 7x

~Simplify

7 < -7x

~Divide 7 to both sides

7/-7 < 7x/-7

~Simplify

-1 > x

Answer:

x < -1

Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />56 < 7(7 - x)

56 < (7 * 7) + (7 * -x)

56 < 49 - 7x

<u>Step 2:  Subtract 49 from both sides</u>

<u />56 - 49 < 49 - 7x- 49

7 < -7x

<u>Step 3:  Divide both sides by -7</u>

<u />7 / -7 < -7x / -7

Since you divided by a negative, you must flip the sign.

<u />7 / -7 < -7x / -7

-1 > x

Answer:  x < -1

The larger leg of a right triangle is 3 cm longer than its smaller leg. The hypotenuse is 6 cm longer than the smaller leg. How
dlinn [17]
For rigt triangle with legs legnth a and b and hypotnuse legnth c

a^2+b^2=c^2

we are given
larger leg is 3 longer than smaller leg
hypotnuse is 6 longer than smaller
find smaller

ok so

first pick a smaller leg
lets say b is smaller
longer leg is 3 more than shorter leg
a is 3 more than b
a=3+b
and

hypontuse is 6 more than shorter
c=6+b

sub 3+b for a and 6+b for c in oroiginal equation'

a^2+b^2=c^2
(3+b)^2+b^2=(6+b)^2
9+6b+b^2+b^2=36+12b+b^2
2b^2+6b^2+9=b^2+12b+36
minus (b^2+12b+36) from both sides
b^2-6b-27=0
factor
(b-9)(b+3)=0
set equal to zero

b-9=0
b=9

b+3=0
b=-3
fasle, legnths cannot be negative


answer is shorter side=9 cm

The length of one side of a square city block is 462 meters. what is the perimeter of the block
trapecia [35]
The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.
