Can someone plz help me find the area for this composite figure plzzzz I beg u

Anarel [89]

$S_1 = \frac{a+b}{2}h = \frac{7+9}{2}*5=\frac{18*5}{2}= 9 * 5 = 45~m^2$

$S_\triangle = \frac{ab}{2} = \frac{5*9}{2} = \frac{45}{2} = 22,5~m^2$

$S = S_1 + S_\triangle = 45 + 22,5 = 67,5~m^2$

Answer: 67,5 m².

Calculate the value of each expression:<br> (-8)•(-2/3)<br> SHOW YOUR WORK:

inna [77]

Answer: $\frac{16}{3}$

Step-by-step explanation:

For this exercise it is important to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

In this case, given the following expression:

$(-8)(-\frac{2}{3})$

You can idenfity that both factors are negative. Then, the product (The result of the multiplication) will be positive.

Then, in order to get the product, you need to multiply the numerator of the fraction by -8. So, you get:

$\frac{(-2)(-8)}{3}=\frac{16}{3}$

You can notice that the numerator and the denominator of the fraction obtained cannot be divided by the same number; therefore, the fraction cannot be simplified.

If five times a number plus two is 17 what is the number

Mila [183]

5 times a number plus two is 17

5(x) + 2 = 17

isolate the x, do the opposite of PEMDAS

(Note: What you do to one side you do to the other, because of equal sign)

5x + 2 (-2) = 17 (-2)

5x = 15

5x/5 = 15/5

x = 3

artcher [175]

Find the price for each apple by dividing the price over the number of apples. At Quixk Market, each apple costs 1.05/3 or $.35 per apple.
At Stop and Save, you can buy one apple for 2.45/5 or $.49.
The Quick Market is a better buy because It has $.15 less for each apple.
Hope this helps.
