x = 6
4x2−10x=84
Step 1: Subtract 84 from both sides.
4x2−10x−84=84−84
4x2−10x−84=0
Step 2: Factor left side of equation.
2(2x+7)(x−6)=0
Step 3: Set factors equal to 0.
2x+7=0 or x−6=0
x=

A biologist determined that there were 42 oak trees in a 5-acre forest. How many oak trees would be expected on 40 acres of identical habitat?
Answer:
336
Step-by-step explanation:
Using arithmetic operation, the number of oak trees on the land which is of identical habitat would be 336.
Using the relation:
5 acres = 42 trees - - - - - (1)
40 acres = t - - - - - (2)
Cross multiply
5t = 42 × 40
5t = 1680
t = 1680 / 5
t = 336 oak trees
Therefore, the Number of oak trees would be 336

Find the value of x
(8x-1) (4x+7)
Answer:
The value of x = 7
Step-by-step explanation:
Given the right triangle
Right angle = 90°α = (4x+7)°β = (8x-1)°We know that the sum of angles of a triangle is 180°.so
Right angle + α + β = 180°
90° + 4x+7 + 8x-1 = 180
Group like terms
[tex]4x+8x+90+7-1=180[/tex]
Add similar elements: :4x+8x=12x
[tex]12x+90+7-1=180[/tex]
[tex]12x+96=180[/tex]
[tex]12x=84[/tex]
Divide both sides by 12
[tex]\frac{12x}{12}=\frac{84}{12}[/tex]
[tex]x = 7[/tex]
Therefore, the value of x = 7

Answer:
It is clear from the graph,
The value of x=-6 at y=0.Thus, x=-6 is the zero of g.
Step-by-step explanation:
A zero of the linear function 'g' on the graph of a linear function can be observed where the 'y-value' is zero.
In other words,
A point where the line tends to cross the x-axis is called the x-intercept.x-intercept can be observed by setting the y=0 and determining the value of x at y=0It is clear from the graph,
The value of x=-6 at y=0.Thus, x=-6 is the zero of g.

Which decimal represents the portion that is NOT shaded?
0.003
0.03
0.3
3.0
Write how u solved it
Answer:
0.3
Step-by-step explanation:
Answer:
3.0
Step-by-step explanation:
Here we have a rectangle split into ten parts with 7/10 shaded in blue. The question asks what decimal represents the portion, alright, let's go down the list.
0.003 is also known as 3 thousandths, meaning that we would need a thousand little squares as our figure. Clearly this isn't the case, so 0.003 is wrong.
0.03 is also known as 3 hundredths, meaning that we would need a hundred little squares as our figure, this also isn't the case, so 0.03 is wrong.
0.3 is known as 3 tenths, yes this could represent our figure, but it doesn't represent the finished portion, which would be 1.0, this means that only one part will be shaded in the figure we have now, leaving it to be wrong.
This leaves us with 3.0
