Let's draw the diagonals of the square. The square is being divided by 4 right triangles. & these right triangles are also isosceles (the diagonals of a square intercepts each other in the middle).
The area of each right triangle = (6 x 6) / 2 = 18 yard² & the 4 right triangles => 4x 18 = 72 yd²

What is the value of x in the equation x – y = 30, when y = 15?

slamgirl [31]

Since −y does not contain the variable to solve for, move it to the right side of the equation by adding y to both sides.x=y+30

What is f(g(x)) for x > 5?

mel-nik [20]

Answer:

$\large\boxed{B.\ 4x^2-41x+105}$

Step-by-step explanation:

$f(x)=4x-\sqrt{x}\\\\g(x)=(x-5)^2\\\\f(g(x))\to\text{put}\ x=(x-5)^2\ \text{to}\ f(x):\\\\f(g(x))=f\bigg((x-5)^2\bigg)=4(x-5)^2-\sqrt{(x-5)^2}\\\\\text{use}\\(a-b)^2=a^2-2ab+b^2\\\sqrt{x^2}=|x|\\\\f(g(x)=4(x^2-2(x)(5)+5^2)-|x-5|\\\\x>5,\ \text{therefore}\ x-5>0\to|x-5|=x-5\\\\f(g(x))=4(x^2-10x+25)-(x-5)\\\\\text{use the distributive property:}\ a(b+c)=ab+ac\\\\f(g(x))=(4)(x^2)+(4)(-10x)+(4)(25)-x-(-5)\\\\f(g(x))=4x^2-40x+100-x+5\\\\\text{combine like terms}\\\\f(g(x))=4x^2+(-40x-x)+(100+5)\\\\f(g(x))=4x^2-41x+105$

Solve for x. x^2+4x-21=0 A. -3, -7 B. -3, 7 C. 3, -7 D. 3, 7

Free_Kalibri [48]

Answer:

x = 3 and x = -7

Step-by-step explanation:

The method I used is the x method, where you place the constant on the top and the coefficient of the second term on the bottom. From there, you find two numbers that multiply to get the top number (21) and add to give the bottom number (4).

You should get -3 and 7. You should be able to rewrite the equation as so:

(x - 3) (x + 7)

Set both equal to zero separately and solve:

x - 3 = 0

x = -3

x + 7 = 0

x = -7
