Area of a Rectangle = Length * Width
Length= 17 yards
Width= ?
L*W=A
17 yards * 2 yards = 34 square yards
Answer:
x = 12.75
Measure of angle YXZ = 49.75 degrees
Step-by-step explanation:
<em>Complementary angles have a sum of </em><em>90</em><em> degrees so we </em><em>add </em><em>them and set them equal to </em><em>90.</em>
3x + 2 + 5x - 14 = 90
<em>Combine like terms</em>
8x - 12 = 90
<em>Add </em><em>12</em><em> to both sides</em>
8x = 102
<em>Divide both sides by </em><em>8</em><em> to isolate </em><em>x</em>
x = 12.75
Measure of angle YXZ = 49.75 degrees
3 hours times 40 =120 plus half of 40, so 20 plus 120 = 140km.

4y - y(3 - 7y) + 5 + 2(8 - y)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute parenthesis: 4y - 3y + 7y² + 5 + 16 - 2y
- Combine like terms (y): 7y² - y + 5 + 16
- Combine like terms: 7y² - y + 21
Answer:
200ft^2
Step-by-step explanation:
From the first sentence;
L = 2B
Perimeter of a rectangle = 60ft
P = 2[ L +B ]
substitute as follows;
60 = 2( 2B + B)
60 = 2(3B)
60 = 6B
B = 10ft
To find L
L = 2B
L = 2*10
L = 20 ft
Area of a rectangle = LB
= 20×10
=200ft^2
