Associative Property is a rule that refers to grouping. The rule is "<span>a + (b + c) = (a + b) + c</span><span>".
</span>
The correct answers are (A) and (D)
(A) = <span> (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]
(D) = </span><span>–7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)</span>
Answer:
4.16, 4.6, 4.608, 8.320
Step-by-step explanation:
Answer:
B. 2 + 6x and 2(3x + 1) Choose
D. 3x and 4(x + 1) – x – 4 Choose...
E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...
Step-by-step explanation:
A. 3x + 14 – x + 112 and 4x + 134 Choose...
3x + 14 - x + 112
= 2x + 126
And
4x + 134
Not equivalent
B. 2 + 6x and 2(3x + 1) Choose...
2 + 6x
And
2(3x + 1)
= 6x + 2
Yes, equivalent
C. 3(x + 1) – (1 + x) and 2x + 3 Choose...
3(x + 1) - (1 + x)
3x + 3 - 1 - x
2x + 2
And
2x + 3
No, not equivalent
D. 3x and 4(x + 1) – x – 4 Choose...
3x
And
4(x + 1) - x - 4
= 4x + 4 - x - 4
= 3x
Yes, equivalent
E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...
5.5 + 2.1x + 3.8x - 4.1
1.4 + 5.9x
And
1.4 + 5.9x
Yes, equivalent
You can just multiply the area of the base times the height. The base is a triangle which has an area of bh/2. If we let b=base, h=height (of the triangle base) and H=the height of the prism, then:
V=Hhb/2, in this case:
V=17*2*1/2
V=17m^3
