Draw a line from(-4,3) to (4,3).

a square and triangle is shown.

find the area of the square and the triangle

FORMULA

square-length*width

7*8=56

triangle-(hight*base)/2

(8*3)/2=12

56+12=68

The answer is 68,
To find the area of a trapezium, you need to use the formula:
1/2(a+b)h
A and b being the parallel lines and h being the height.

0.5 x 17 x 8 = 68

Hope this helps x

The circle given by : x^2 + y^2 - 6y - 12 = 0 can be written as:

deff fn [24]

Step-by-step explanation:

Given equation of circle is,

${x}^{2} + {y}^{2} - 6y - 12 = 0 \\ by \: compairing \: it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\2 g = 0 \: or \: g = 0 \\ 2f= - 6 \\ or \: f= - 3 \\ c = - 12$

again the another form of circle is,

${x}^{2} + {(y - k)}^{2} = 21 \\ or \: {x}^{2} + {y}^{2} - 2ky + {k}^{2} - 21 = 0 \\ by \: compairing \:it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\ g = 0 \\f = - k \\ c = {k}^{2} - 21$

now equating the values of f in both equations,

-k=-3

i.e. k=3

therefore k=3

there are 76 students in chorus. the number of girls in the chorus is 12 more than triple the number of boys.

lora16 [44]

Girls= 12+3b
boys=b

boys+girls=76

12+3b+b=76;
12+4b=76
-12 -12
4b=64
÷4. ÷4

b=16
