D. 10.48 because when two negatives are next to each other it becomes a positive and you add.
Turn it into a improper fraction and then multiply both the numerator and denominator together!
So like 1 1/2 x 2 1/2
Turn that into improper fractions and get 3/2x5/2
then you get 15/2 which is 7 1/2
Tony because he spent $19 while Mario spent $18. To explain, you would multiply 3 by $4 because Tony bought 3 of the $4 packs of pencils. Therefore, he would have spent $12. In addition, add $7 to $12, you get $19. On the other hand, Mario bout 4 of the $6 binders. That would mean he spent $24 on binders However, he had a $6 coupon which means he can take $6 off the total price of $24. That would mean subtracting $6 from $24. That would get Mario $18
Answer:
Step-by-step explanation:
Sum = 20
Product = 5*20 = 100
Factors = 10 , 10 {10*10 = 100 ; 10+10 = 20}
5x² + 20x + 20 = <u>5x² + 10x</u> + <u>10x + 10*2</u>
= 5x(x + 2) + 10(x + 2)
= (x + 2)(5x + 10)
y = -3x - 2
Since a < 0 we have a decreasing line, so it can be only the first or the last
And if we solve the equation for y = 0 we have
0 = -3x - 2
3x = -2
x = -2/3
So, the last one is the right
