The area of the square pyramid is 105 sq inches.

Step-by-step explanation:

Given,

The base of the pyramid (b) = 5 inches

The height (h) = 8 inches

To find the area of the square pyramid.

Formula

The area of the square pyramid = 2bh + b^{2}

Now,

The area of the square pyramid = 2×5×8 + 5^{2} sq inch

= 105 sq inches

Hence,

The area of the square pyramid is 105 sq inches.

Answer:

Area of the Square pyramid=108.8 inches^2

Step-by-step explanation:

Area of a a square pyramid:

                                    a^2+2a\sqrt{\frac{a^2}{4}+h^2 }

Base: side(a)= 5 inches

Height=8 inches

Putting the values in the formula:

Area =    5^2+2(5)\sqrt{\frac{5^2}{4}+8^2 }

             =25+10\sqrt{\frac{25}{4}+64 }\\\\ =25+10\sqrt{6.25+64}\\\\ =25+10\sqrt{70.25}\\\\ =25+10(8.38)\\\\=25+83.8\\\\=108.8inches^2

Area of the Square pyramid is: 108.8 inches^2

Which expression is equivalent to -4/7 - 8/9 + 4/7 - 9/8
olya-2409 [2.1K]

Answer:

<em>I misunderstood the question before, but here are two expressions equivalent to -4/7 - 8/9 + 4/7 - 9/8. </em>

71/72 + 70/72 +4/72

-1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8

<em>Solved: -2 1/72</em>

Step-by-step explanation:

I could simply take the answer you get when combining all of the fractions, and I can make a new expression out of it. For example, I could use: 71/72+ 70/72+4/72. Or I could break apart all of the original fractions into smaller fractions. Example: -1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8.

<em>To solve: Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.</em>

<em>Hope this helps!</em>
