Choose a number sentence is that illustrates distribute property of multiplication over addition 2×7+8 = 2+7×2+8
Agata [3.3K]

Answer:

(b)\  2 * (7 + 8) = (2 * 7) + (2 * 8)

Step-by-step explanation:

Given

(a)\ 2 * (7 + 8) = (2 + 7) * (2 + 8)

(b)\  2 * (7 + 8) = (2 * 7) + (2 * 8)

(c)\ 2 * (7 + 8) = (2 * 7) + 8

Required

Which illustrates distributive property of multiplication over addition

The property states that:

a(b + c) = a * b + a * c

By comparison

a = 2\ b = 7\ c = 8

So, we have"

2(7 + 8) = 2 * 7 + 2 * 8

2(7 + 8) = (2 * 7) + (2 * 8)

Which sequence below represents an exponential sequence? A) {2, 6, 10, 14, 18,...} B) {3, 5, 9, 16, 24,...} C) {4, 8, 24, 96,...
Flura [38]

Answer:d

Step-by-step explanation:

Clearly from observation option D is the exponential sequence

256,64,16,4 is decreasing exponential function

\Rightarrow \frac{256}{64}=\frac{4^4}{4^3}=4

\Rightarrow \frac{64}{16}=4

for other option they simply follow an AP

2,6,10,14,18

common difference d=4

<em>4</em><em>5</em><em>m</em><em>+</em><em>9</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em><em>m</em>

Step 2) Subtract <em>4</em><em>5</em><em>m</em><em> </em>from both sides

<em>9</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em><em>4</em><em>5</em><em>m</em>

the height of an equivalent triangle is 15cm and it's perimeter is 36cm find the area of the triangle​
OlgaM077 [116]

Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

so

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²
