Step-by-step explanation:
Answer:
184
Step-by-step explanation:
Increased by 15%: there are 15%, or 0.15 more bears.
To solve, we need to add the number of bears last year, and the number of new bears in the park.
1 * 160 + 0.15 * 160 =
1.15 * 160 =
184 bears
Okay so the area of a rectangle x by y with a border of width b will be:
A=(x+2b)(y+2b)
A=xy+2bx+2by+4b^2 we are told that A=320, x=11, and y=15 so now we have:
320=165+22x+30x+4x^2, now I am using x as the border width...
4x^2+55x+165=320 is the equation that they listed..
...
4x^2+55x-155=0 using the quadratic formula for efficiency...
x=(-55±√5505)/8 since x>0
x≈2.399 which for some unknown (incorrect) reason they rounded to
x=2.5
So in short, your answer is a)
Substitute everything in first
3(-2)-1-3(-2)
Then simplify
-6-1+6 = -1
The answer is -1
