Area is equal to length times width, so we can use this over here:

Area = lw
Area = (x+7)(x+1)
Area = x^2+x+7x+7
Area = x^2+8x+7

Hope this helps!! :)

How do I find x and y using what is in the equation

Tatiana [17]

y is part of a right angle on line AB

a right angle = 90 degrees

90-47 = 43 degrees

y = 43 degrees

a straight line = 180 degrees

180-47 = 133 degrees

x = 133 degrees

Solve for b. a+3b=5c-9

notka56 [123]

Answer:

(5c-9-a)/3

Step-by-step explanation:

1. subtract a from both sides to isolate the variable and its coefficient

5c-9-a = 3b

2. divide both sides by 3 to isolate b because 3b/3 = b

(5c-9-a)/3 = b

Which inequality is true when n=4?

Nadusha1986 [10]

To find out which inequality is true, we need to plug in n=4.

$2n>6$
$2(4)>6$
$8>6$

And since 8 is really greater than 6, this inequality is true! :)

$n+3$
<u /> $4+3 < 7$
$7 < 7$

7 is not less than 7. So this inequality is false.

$9- n \geq 13$
$9-4 \geq 13$
$5 \geq 13$

5 is not greater than or equal to 13, so this inequality is false

$\frac{n}{12} \geq 3$
$\frac{4}{12} \geq 3$
<u /> $\frac{1}{3} \geq 3$

And 1/3 is not greater than 3, so this inequality is also false.
