Answer: 118 degrees

Step-by-step explanation:

Angles on the opposite sides of rhombus will always be equal and the sum of all the angles of quadrilaterals are 360 degrees so we get the equation

2u - 70 + u + 52 + 2u - 70 + u + 52 = 360

6u - 36 = 360

6u = 396

u = 66

But, 66 is not the answer, as they want to find the angle D AKA u + 52 which is 66 + 52 = 118 degrees

Apply the distributive property to create an equivalent expression.
rjkz [21]

Answer:

4x-8+4y

Step-by-step explanation:

We are given that an expression

4(x-2+y)

We have to find an equivalent expression using distributive property .

Distributive property:

a\cdot (b+c)=a\cdot b+a\cdot c

Using the property

4(x-2+y)=4(x-2)+4\cdot y

4(x-2+y)=4x+4(-2)+4y

4(x-2+y)=4x-8+4y

Hence, the equivalent expression  of the given expression is given  by

4x-8+4y
