In its present form, the question has no answer.
It's on account of the number that's supposed to be there
before the word "degrees" but isn't.
Answer:
Step-by-step explanation:
x² + 3x - 10 = 0
We have to find two numbers which multiply to -10 and have a sum of -3.
Two great numbers which match these conditions are 5 and -2!
5 + (-2) = 3
5 * (-2) = -10
So, now we can factor.
(x + 5)(x - 2) = x² + 3x - 10, right?
Now we know A and B are 5 and -2. (Please keep in mind these are not the solutions or the roots to the quadratic. When solving for the roots in a quadratic, you have to find numbers which make the equation equal to zero. Anything multiplied by zero is zero, so when you input a value into the parentheses which makes the value inside the parentheses zero, the whole equation becomes zero and this is why quadratics have up to two solutions because up to two values can make the equation equal to zero.)
(X,Y)=(39,69) is the answer
The van will need 25 gallons of gas for it to travel 550 miles. This is calculated by dividing 10 gallons to 220 miles to get the miles per gallons, which in this case is 22 miles per gallon. Then we have to divide 550 miles by 22 miles per gallon to get the total gas consumption, which is 25 gallons.
Answer:
The quotient will be -1
Step-by-step explanation:
2.6 ÷ -2.6
= 2.6/-2.6
= 1/-1
= -1
