This expression is a perfect square trinomial. It has two answers but they don't have to be different. In this case it has to be the same - because it is a perfect square trinomial.
Answer:
Hope it helps!
Step-by-step explanation:
Sub y=5x into y=2x+3
so
5x=2x+3
3x=3
x=1
plug x=1 into y=5x
y=5
Checking work
Plug (1,5) into y=2x+3
5=2(1)+3
5=5
Plug (1,5) into y=5x
5=5(1)
5=5
Answer:
A2: 4*4*4 = 64 cm³; 6*6*6 = 216 cm³; etc...
B2: 7*4.5*4 = 126 cm³; 10.5*6*2 = 126 cm³; etc...
Step-by-step explanation:
So in A2 you have cubes, so l=b=h, and only one has to be given, called the "length of side".
In B2 they are different, hence there are 3 rows with l, b and h. But still you multiply them l x b x h
Answer:
B. √6900
Step-by-step explanation:
The square length of hypotenuse is equal to sum of square length of two legs let x represent the other leg
130^2 = 100^2 + x^2
16900 = 10000 + x^2 subtract 10000 from both sides
6900 = x^2 find the root for both sides
x = √6900
