The last one (D) is not right. The corresponding lines share the same ratio but they need not be equal.
D <<<< answer.
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 2 + 1 = 3 parts , thus
81 cm² ÷ 3 = 27 cm² ← value of 1 part of the ratio
2 parts = 2 × 27 = 54 cm²
Area of A = 54 cm² and area of B = 27 cm²
The side of the original square = = 9 cm
The width of both rectangles is 9 cm ( width remains unchanged after cut )
Thus
Rectangle A
9 × length = 54 ( divide both sides by 9 )
length = 6 cm
Rectangle B
9 × length = 27 ( divide both sides by 9 )
length = 3 cm
Rectangle A → length = 6 cm, width = 9 cm
Rectangle B → length = 3 cm , width = 9 cm
Answer:
y=8
Step-by-step explanation:
Multiply both sides of the equation by 4.
y−64=−56
Add 64 to both sides.
y=−56+64
Add −56 and 64 to get 8.
y = 8
and have a good day as well
First, we have to find what x equals. If all the angles add up to 180°, then we can make the equation 2x+2x+6x=180. If we combine like terms, the equation simplified to 10x=180. If we divided both sides by 10, we get that x=18. Now, we can plug in x in 2x to get 2(18). 2×18=36. Angle C is 36°!
