Answer:

106 cm²

Step-by-step explanation:

the surface area is the sum of the areas of the faces of the prism

area of 2 rectangles (left/ right ) = 2 × 7 × 5 = 70 cm²

area of central rectangle = 3 × 7 = 21 cm²

area of 2 congruent triangles = 2 × \frac{1}{2} × 3 × 5 = 3 × 5 = 15 cm²

surface area = 70 + 21 + 15 = 106 cm²

Grade 9 math plzz helpp a or b or c or d
hram777 [196]

Answer:

g(x) = 3^{x -4}

Step-by-step explanation:

Given

f(x) = 3^x

g(x) = f(x) 4 units left

Required

Find g(x)

When a point is translated 4 units left, the rule is:

x \to x - 4

So, we have:

g(x) = f(x-4)

f(x-4) is calculated as:

f(x-4) = 3^{x -4}

Hence:

g(x) = 3^{x -4}

Ket [755]

Answer:

Option (2)

Step-by-step explanation:

Option (1).

2(\frac{2}{5}x+2)=2\frac{2}{5}x+1

\frac{4x}{5}+4=\frac{12}{5}x+1

Therefore, both the sides of the expression are not equal.

False.

Option (2).

2(\frac{2}{5}x+2)=\frac{4}{5}x+4

\frac{4x}{5}+4=\frac{4}{5}x+4

True.

Option (3).

2(\frac{2}{5}x+4)=\frac{4}{5}x+2

\frac{4}{5}x+8=\frac{4}{5}x+2

False.

Option (4).

2(\frac{2}{5}x+4)=2\frac{2}{5}x+8

\frac{4x}{5}+8=\frac{12}{5}x+8

Both the sides are not equal.

False.
