Hey there!

Answer:\boxed{b=2}

Explanation:

2b+5=9

Let's start off by subtracting 5 from both sides of the equation.

2b+5-5=9-5\\2b=4

Now let's divide both sides by 4.

\frac{2b}{2}=\frac{4}{2}=2\\ b=2

\boxed{b=2}\text{ is your answer.}

Hope this helps!

Answer:

<h2>S.A. = 234 mm²</h2>

Step-by-step explanation:

The formula of a surface area of a rectangular prism:

S.A.=2(lw+lh+wh)

l - length

w - width

h - height

We have l = 15 mm, w = 3 mm, h = 4 mm. Substitute:

S.A.=2(15\cdot3+15\cdot4+3\cdot4)=2(45+60+12)=2(117)=234

Wegnerkolmp or someone who can explain maths please<br> I need a proper explanation

Answer: 66 degrees

Explanation:

Check out the attached image below. Figure 1 is the original image without any additions or alterations. Then in figure 2, I extend segment BC to form a line going infinitely in both directions. This line crosses segment DE at point F as shown in the second figure.

Note how angles ABC and DFC are alternate interior angles. Because AB is parallel to DE (given by the arrow markers) this means angle DFC is also 24 degrees

Focus on triangle DFC. This is a right triangle. The 90 degree angle is at C.

So we know that the acute angles x and 24 are complementary. They add to 90. Solve for x

x+24 = 90

x+24-24 = 90-24

x = 66

That is why angle CDE is 66 degrees
