Two triangles are similar if and only if all corresponding angles are equal (congruence), even if the corresponding sides are equal or not, therefore the answer is true because ΔJKL and ΔRST are similar and the statement above demands that "it must be", namely, this is a sufficient condition.

1/2(-9 + y)=2.5 solve for why. Please show me your steps

Oksi-84 [34.3K]

Answer:

Y = 14

Step-by-step explanation:

1/2(-9 + y) = 2.5

1/2 * -9 = -4.5

1/2 * y = 0.5y

Add 6x+2y + y2 +6x+2y +y2+ 4x2+ x2+y

Alexus [3.1K]

Answer:

5 x^2 + 2y^2 + 12x + 5y

Step-by-step explanation:

6x + 2y +y^2 + 6x + 2y + y^2 + 4x^2 + x^2 + y

12x +y^2 + 4y + y^2 + 4x^2 + x^2 + y

12x + 2y^2 + 4x^2 + x^2 + 5y

2y^2 + 5x^2 + 12x + 5y

5 x^2 + 2y^2 + 12x + 5y

A rectangular prism has a length of 114 yards, a width of 212 yards, and a height of 4 yards.

drek231 [11]

Answer: 96,672 yards cubed

Step-by-step explanation: The formula for the Volume of a rectangar prism is Length×Width×Height

114yds × 212yds × 4yds = 96,672yds^3

Its already in simplest form since its all yards

But, you can also convert it into miles

In which 1 mile = 1760 yards

So you'd divide 96670 by 1760, and what ever answer youget would be the answer in miles
