Answer:
4x^2+24x=4
Step 1:
make the coefficient of x² as 1, divide both sides by 4
x² +6x =1
Step 2:
take half of coefficient of x, square it and add it to both sides
half of 6 is 3 and 3²=9, so add 9 to both sides
x² +6x+9=1+9
x²+6x+3²=10
(x+3)²=10
now when we take square root we will get both + and - √10 on right side
x+3= +√10
x+3=-√10
solving for x
x=+√10-3

Answer:
d. The triangles are not similar because 6/13 ≠ 8/20.
Step-by-step explanation:
△ABC is similar to △DEF ,If the length of their corresponding sides are proportional.
ie : 6/13 = 8/20 = 10/25
Since , 6÷13 = 0.461538461538 ≠ 0.4 = 8÷20
Then
6/13 ≠ 8/20
Therefore , the triangles are not similar.

study is ur time waste
The plane must be 3.38 miles away from the runway to begin the descent. The equation I used was "y = -0.1111111x + 0.3755682", 0.37~ being the height in feet (in miles) and -0.11~ being the descent. The x-intercept is located at 3.38.
ANSWER
Rewrite and make substitution.
EXPLANATION
Since Harriet calculated 27 divided 4 and had 6.75.
This means that:
![\frac{27}{4} = 6.75](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%7D%7B4%7D%20%20%3D%206.75)
Now we want to find
![\frac{270}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B270%7D%7B4%7D%20)
without divide.
Therefore we need to rewrite the expression so in terms of
![\frac{27}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%7D%7B4%7D%20)
so that we can substitute.
This will give us;
![\frac{270}{4} = \frac{27}{4} \times 10](https://tex.z-dn.net/?f=%20%5Cfrac%7B270%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B27%7D%7B4%7D%20%20%5Ctimes%2010)
This implies that,
![\frac{270}{4} = 6.75 \times 10](https://tex.z-dn.net/?f=%5Cfrac%7B270%7D%7B4%7D%20%20%3D%20%206.75%20%20%5Ctimes%2010)
![\frac{270}{4} = 67.5](https://tex.z-dn.net/?f=%5Cfrac%7B270%7D%7B4%7D%20%20%3D%2067.5)
