Answer:
D) Distributive
Step-by-step explanation:
2(x + 7) + 3x = 12
You need to put the equation in its simplest form.
That is why you need to distribute first.
Outcome:
2x + 14 + 3x = 12
Answer:
x= -4
Step-by-step explanation:
2x+4=6x+20
so 2x-6x=20-4
divide both sides by -4
-4x/-4 = 16/4
=-4
Answer:
It should look like, 14y + 5.
Step-by-step explanation:
These are usually hard to explain but, you have to look at the problem you are given in a certain way. Product means multiplication, and more than means addition. When it gives you the product of a number and a variable, always combine the two since putting a number next to a variable means the same thing as multiplying the two together. Then, it tells you that "more than" five, which as I previously said, it would mean addition, so simply add five to the end of the equation. :)

Area of rhombus = d1 × d2
= 12 × 16 = 192
Area of rhombus is also b × h
Assuming the side as base,
192 = b × h
192 = 10 × h
h = 192/10 = 19.2 in
