Answer:

48.25 m²

Step-by-step explanation:

Surface area = base‘area + lateral area

base‘area = the area of the triangle of base 4.3 and height 5

lateral area = 3×(Area of a trianglre of base 5 and height 5)

base‘area = (5×4.3)÷2

lateral area = ((5×5)÷2)×3

then

Surface area = ((5×5)÷2)×3+(5×.,3)÷2 = 48.25

If (x + 7) is a factor of f(x), what is the value of f(-7)?

rewona [7]

Answer:

The answer is 0.

Step-by-step explanation:

Simply plug in -7 for x as they want to see what the value of the function is when x=-7.

You can then just add -7 and 7.

7 + -7 = 0

So the answer is 0

The diagram show a 5cm x 6cm x 7cm cuboid pls help you

kotegsom [21]

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

$d=\sqrt{l^2+w^2+h^2}$

1.) Plug in all the values for l, w, and h

$d=\sqrt{5^2+6^2+7^2}$

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

$d=\sqrt{25+36+49}$

3.) Add the terms

$d=\sqrt{110}$

4.) Simplify

$d = 10.488$

5.) Round to one decimal place

d ≈ 10.5
