6 + 8 div by 2 = 7 is incorrect. Why? Because Order of Operations rules require that we mult. and div. BEFORE add. or subtr.
8 must be div by 2 FIRST: Then, on the left side, you have 6 + 4.
6 and 4 does not = 7.
Rather, 6 + 4 = 10
Area of the rectangle is 10.27 cm²
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x, then length = 4 + 3x. Find the dimensions if perimeter = 18.4 cm
Perimeter = 2(length + width)
⇒ 18.4 = 2 (x + 4 + 3x)
⇒ 18.4 = 2(4x + 4)
⇒ 18.4 = 8x + 8
⇒ 8x = 10.4
⇒ x = 10.4/8 = 1.3
∴ 4 + 3x = 4 + 3×1.3 = 7.9
- Step 2: Find area of the rectangle.
Length = 7.9 cm and width = 1.3 cm
⇒ Area = length × width
= 7.9 × 1.3 = 10.27 cm²
Answer:
Is it going to be $19.55?
Step-by-step explanation:
Answer: 22
Step-by-step explanation:
Lines a and b are cut by transversal f.
Then from the given information,
[ If two parallel lines are cut by a transversal then, the alternate exterior angles are equal. ]
Hence, the value of x so that lines a and b are parallel lines cut by transversal = 22
Answer:
Step-by-step explanation:
opposite= 8 : the length opposite angle c
adjacent=15 : the length next to angle c, not the hypotenuse
hypotenuse= 17 : the hypotenuse will always be opposite the right angle
