Can someone please on this , I need help on this too !!
Answer:
b=4
Step-by-step explanation:
Lets a be lenght and b width. From text we have:
a=b+4
a*b=32
Put the first equation in the 2n, we get:
(b+4)b=32
b^2+4b-32=0
b^2+8b-4b-32=0
b(b+8)-4(b+8)=0
(b+8)(b-4)=0
So it must be b=-8 or b=4. We know that width cannot be negative, so it is 4.
First
360 divided by 12=30
alex got=30 multiply 5=150
ben got=30 x 7 =210
so ben got 60 more than alex
Answer:
x = 5.5
Step-by-step explanation:
Using a trig ratio, you can use sin, which is opposite over hypotenuse. 
Now, multiply both sides by 11

this simplifies to x =
or 5.5.
Since sin30 is
radians, it can be written as
.
Answer:
270
Step-by-step explanation:
The formula for finding the area of a triangle is <em>base · height ÷ 2, </em>or 
After plugging in the numbers given to the formula, we find that the area of the triangle is 27.
Then to account for the length, we multiply the area of the triangle by 10.
This gets us to 270.
