elena-s [515]

Answer:

4x2 + 3x + 4

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 4 • 4 = 16

Step-2 : Find two factors of 16 whose sum equals the coefficient of the middle term, which is 3 .

-16+-1=-17

-8+-2=-10

-4+-4=-8

-2+-8=-10

-1+-16=-17

1+16=17

2+8=10

4+4=8

8+2=10

16+1=17

Nostrana [21]

Answer:

10 problems

Step-by-step explanation:

This is the answer because:

1) We have to solve for what 20% of 50 is since she finished 20% of her test:

20% of 50 = 10

$\frac{2}{10}$ × $\frac{50}{1}$ = $\frac{100}{10}$ = 10

Therefore, the answer is 10 problems.

Hope this helps! :D
