Answer:
The value of x is -9, 3/4 and 3.
Step-by-step explanation:
In order to find the value of x, tou have to let f(x) equals to 0 :
Let f(x) = 0,
(x-3)(x+9)(4x-3) = 0
x - 3 = 0
x = 3
x + 9 = 0
x = -9
4x - 3 = 0
4x = 3
x = 3/4
Answer:
picture: the one with the triangle in red on the base (first picture of box)
Equation: a^2 + 11^2 = c^2
Step-by-step explanation:
as we can see for the first one, the equation we see is 20^2 + 8^2 = c^2, so you look for the picture with those numbers on the triangle.
and to find the equation we look at the picture and see that in the triangle the numbers are 11 and a. And we know the equation has to be 11^2 + a^2 = c^2 And see if that equation is there

Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
