The answer is 80. This is because we can find the area of one of the triangles by (4*8)/2 = 16. We multiply this by 4 since there are 4 triangles. 16*4 = 64. Now finally, we add the area of the base to this value. 4*4+64=80. Therefore the answer is 80 cm^2

YOO ITS 4AM AND I HAVE CLASS IN TWO HOURS I NEED HELP -4(7a+7)-2a=92

lana66690 [7]

- 4 ( 7a + 7 ) - 2a = 92

- 28a - 28 - 2a = 92

- 28a - 2a - 28 = 92

Collect like terms

- 30a - 28 = 92

Add both sides 28

- 30a - 28 + 28 = 92 + 28

- 30a = 120

Divide both sides by - 30

- 30a ÷ - 30 = 120 ÷ - 30

Helena is baking a cake that requires three and one-half cups of flour. Helena accidentally poured five and one-sixth cups of fl

RUDIKE [14]

Amount of flour Helena accidentally poured $=5\frac{1}{6} =\frac{31}{6}$ cups of flour.

Amount of flour the cake requires $=3\frac{1}{2} =\frac{7}{2}$ cups of flour.

Amount of flour that Helena should take out $=\frac{31}{6} - \frac{7}{2}$

$=\frac{31}{6} - \frac{7 \times 3}{2\times 3}$

$=\frac{31}{6} - \frac{21}{6}$

$=\frac{31-21}{6}$

$=\frac{10}{6}$

$=\frac{5}{3}$

$=1\frac{2}{3}$ cups of flour.

Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)

$f(x)=3x- \frac{1}{2}$
there are no restrictions
all real numbers can be used
all real numbers can result

so the answer is domain and range for both is all real numbers
