Answer:

Below!

Step-by-step explanation:

First, find the area of the two triangle using the formula A= bh/2

A = 10 x 12 / 2

= 120 /2

= 60 cm^2 each triangle

Now find the area of the two side areas using the formula A = bh

A = 3 x 13

= 39 cm^2 each

Find the area of the base strip using A = LW

A = 10 x 3

= 30

Finally you need to add up all the areas to get the surface area

SA = 60(2) + 39(2) + 30

= 120 + 78 + 30

= 228 cm^2

Hope this helps, good luck!

Solve the equation. –x + 8 + 3x = x – 6

saul85 [17]

First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.

Then, since it is a positive number, subtract it from that side and the other side.

On the other side, the x becomes -x.

Add the 6 from the other side to the 8 to make 14.

14 = -x

Divide both sides by -1, to get the answer.

x = -14

Tension needs to eat at least an extra 1,000 calories a day to prepare for running a marathon. He has only $25 to spend on the e

Elden [556K]

Answer:

Yes, he can buy 8 donuts and 4 energy drinks.

Step-by-step explanation:

If Tension is able to buy 8 donuts and 4 energy drinks, then both inequalities would be valid when we use these numbers as inputs. Let's check each expression at a time:

$0.75*d + 2*e \leq 25\\0.75*8 + 2*4 \leq 25\\6 + 8 \leq 25\\14 \leq 25$

The first one is valid, since 14 is less than 25. Let's check the second one.

$360*d + 110*e \geq 1000\\360*8 + 110*4 \geq 1000\\2880 + 440 \geq 1000\\3320 \geq 1000$

The second one is also valid.

Since both expressions are valid, Tension can buy 8 donuts and 4 energy drinks and achieve his goal of having a caloric surplus of at least 1000 cal.
