Find the area of the triangle <br>answer in digital format only

IceJOKER [234]

Answer:

Step-by-step explanation:

Assume that each cell on the grid represents one unit. One can use the formula, ( $A=\frac{(base)(hieght)}{2}$ ) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,

$A=\frac{(11)*(6)}{2}$

$A=\frac{66}{2}$

$A=33$

Reflect the point (-20,4)

Firdavs [7]

Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)

Refrection of (-20, 4) across y-axis gives (20, 4)

Refrection of (-20, 4) across y = -x gives (20, -4)

Refrection of (-20, 4) across y = 7 gives (20, 10)

How would I do this with working ?

san4es73 [151]

You Just want to get Fahrenheit alone on one side of the equal sign. Your teacher forgot to use parenthesis. The correct equation for Celsius to Fahrenheit is: $C= \frac{5}{9} (F-32)$

Which will give you a completely different answer.... $F = \frac{9}{5} C + 32$

****

We will solve it using what is given:

C = (5/9)F - 32

C + 32 = (5/9)F

9(C + 32) = 5F

(9/5)(C + 32) = F

** If they mark you wrong, and try to say the answer is F = (9/5)C + 32 then they shouldn't be teaching math, and you should point out the fact there are no parenthesis around the F - 32 in the given formula.
