Given:

Width = x

Length = x + 3

To find:

Which model and solution is correct for the given situation.

Solution:

Sum of the length and width of a rectangle is more than 15 units.

⇒ width + length > 15

\Rightarrow x + x+ 3 >15 --------------- (1)

This model represents the situation.

Adding x:

\Rightarrow 2x+ 3>15

Subtract 3 on both sides.

\Rightarrow 2x+ 3-3>15-3

\Rightarrow 2x >12

Divide by 2 on both sides.

$\Rightarrow\frac{ 2x }{2}>\frac{ 12}{2}

$\Rightarrow x>6 --------------- (2)

The correct model and solution is represents the situation is

x+x+3>15 ; \text { solution } x>6.

\\ \tt\hookrightarrow p(2)=3(2)^6-5(2)^5-2+7

\\ \tt\hookrightarrow p(2)=3(64)-5(32)+5

\\ \tt\hookrightarrow p(2)=192-160+5

\\ \tt\hookrightarrow p(2)=32+5

\\ \tt\hookrightarrow p(2)=37

20. A rectangle has a length of x + 2 meters and a width of 2x - 5. (A.APR.1)
bija089 [108]

Answer:

A:

2(x + 2) + 2(2x - 5) =

2x + 4 + 4x - 10 =

6x - 6

perimeter = 6x - 6

B:

(x+2)(2x - 5)            expand the brackets:

2x² - 5x + 4x - 10

area = 2x² - x - 10

C:

area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24

perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

brainliest please? x

Plz explain and prove the triangles congruence.
amm1812

Answer:

ΔNAS≅ΔSEN by SSA axiom of congruency.

Step-by-step explanation:

Consider ΔNAS and ΔSEN,

NS=SN(Common ie . Both are the same side)

SA=NE( Given in the question that SA≅ NE)

∠SNA=∠NSE( Due to corresponding angle property where SE ║ NA)

Therefore, ΔNAS ≅ΔSEN by SSA axiom of congruency.

∴ NA≅SA by congruent parts of congruent Δ. Hence, proved.

What is the first term in a geometric sequence if the common ratio is −2 and the sum of the first five terms is 77?
kirza4 [7]
Answer is a1 = 7

Using equation (derived from formula to find sum of values in a geometric series),
77 \:  =  \frac{a(1 - (  { - 2}^{5}))}{1 - ( - 2)}
Hence, solve for a.
