Answer: 9 textbooks
Step-by-step explanation:
25 x 120.00 = 3,000
4,000 - 3,000 = 1,000
9 x 105.00 = 945
1,000 - 945 = 55
The teacher can only buy 9 textbooks since she/he doesn't have enough money to get anymore.
The sum of angles in a triangle is 180°, so we have an equation
2*35° + x = 180°
x = 180°-70° = 110°
The third angle is 110°
The area of the rectangle is 64.8 square .inch
<h3>What is a Rectangle ?</h3>
A rectangle is a polygon with four sides , opposite sides are parallel and equal.
It is given that
A rectangle is divided into exactly 20 congruent squares
If they are lined up the Length is 36 inches
Therefore the length of each square or the side of the square = 36/20
= 1.8 inch
The area of the rectangle will be
20* Side of square * Side of square
=20*1.8*1.8
= 64.8 square inch
The area of the rectangle is 64.8 square .inch

Step-by-step explanation:
(4x + y)² - 2z = 16x² + 8xy + y² - 2z
substituting x = 4, y = -2 and z = 6,
= 16(4)² + 8(4)(-2) + (-2)² - 2(6)
= 16(16) + 8(-8) + 4 - 12
= 256 - 64 - 8
= 184
