Use the zero product property to solve the equation. (4k+5)(k+7)=0
Maru [420]
The zero product property tells us that if we have
xy=0, then we can assume that x and y both equal 0

so

(4k+5)(k+7)=0
we can assume that 4k+5=0 and k+7=0
so

4k+5=0
minus 5 both sides
4k=-5
divide both sides by 4
k=-5/4

k+7=0
minus 7 both sides
k=-7


k=-5/4 or -7

Need help,kinda confused on this. Use the rectangle to find the lengths of the following sides if AC=26 and BC=10. Added picture
yarga [219]

1) Diagonals of a rectangle bisect each other, so AW=13.

2) Since diagonals of a rectangle are congruent, AC=BD. Then, since diagonals of a rectangle bisect each other, DW=13.

3) Diagonals of a rectangle are congruent, so BD=26.

4) Opposite sides of a rectangle are congruent, so AD=10.

5) Using the Pythagorean theorem, BA=24.

2y+7 ÷ -4y - 10 Evaluate the expression below when y = -3
Nina [5.8K]
2y+7÷-4y-10
2(-3)+7÷-4(-3)-10
-6+7÷12-10
\frac{7}{12}-6-10
\frac{7}{12} -16
= \frac{7}{12} - \frac{192}{12} 
=- \frac{185}{12} 
=-15  \frac{5}{12}
