Hello!
The first step is to add the 40 to both sides of the equation because the 40 is negative, and adding a 40 will make it 0.
Hope this helps!

Answers

Let the numbers be x and x+1
x(x+1)=420
x^(2) +x=420
x^(2) +x-420=0
The constant is -420

Answer:

-420

The function f(x) = −x2 − 9x + 10 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent?A: x = 1; the diver jumps in the pool at 1 foot per second
B: x = 10; the diver jumps in the pool at 10 feet per second
C: x = 1; the diver hits the water 1 foot away horizontally from the board
D: x = 10; the diver hits the water 10 feet away horizontally from the board

Answers

Answer
C: x = 1; the diver hits the water 1 foot away horizontally from the board

Explanation
The question requires you to solve for x.
 f(x) = −x² − 9x + 10 

When f(x)=0

−x² − 9x + 10 = 0
                      = x²+9x-10 = 0
The product in this expression is -10
The factors of this expression is 9
Factors are 10 and -1.

x²+9x-10 = x²-1x+10x-10 = 0
               =x(x-1)+10(x-1) = 0
               =(x+10)(x-1) = 0
This means that;
x+10=0      or  x-1=0
x = -10            x = 1.
Since distance can not be negative, x =1.

justin and tyson are beginning an exercise program to train for football season. Justin weighs 150 pounds and hopes to gain 2 pounds per week. Tyson weighs 195 pounds and hopes to lose 1 pound per week. if the plan works in how many weeks will the boys weigh the same amount. what will the weight be

Answers

It will take Justin and Tyson 15 weeks to both be 180 pounds. You just do 150+2*15=180 and then you would do the other one 195-1*15=180 and they both equal the same.
it will take 15 weeks for them to be the same weight.
