r + 4(r - 3)
<em><u>We'll use the distributive property to simplify this.</u></em>
r^2 - 3r + 4r - 12
<u><em>Combine like terms</em></u>
r^2 + r - 12 is the simplified form.
15:42 ??? I think so. Have a good day.
The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°
9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
Answer:
$1040
Step-by-step explanation:
9 ÷ 100 = 0.09 × 500 = 45
45 × 12 = 540
500 + 540 = 1040
