Two triangles can be similar if their corresponding angels are congruent also the corresponding sides are in proportion triangles can be the same shape but not really same size
Answer:
3) D
4) B
5) A
6) 2 (x + 7)
Step-by-step explanation:
3)
D. Distributive Property
The distributive property of multiplication over addition can be used when you multiply a number by a sum.
4)
B. 2 + 8 = 8 + 2
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around.
5)
A. 4 x 1 = 4
The "Multiplicative Identity" is 1, because multiplying a number by 1 leaves it unchanged: a × 1 = 1 × a = a.
6)
3 ( x + 3) - X + 5
3x + 9 - x + 5
2x + 14
2 (x + 7)
Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>
5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>
5x-2x = 15+3
<h3>iii) collect like terms</h3>
3x = 15+3
<h3>iv) add the numbers</h3>
3x = 18
<h3>v) divide both sides of the equation by 3</h3>
