Answer:
[tex]4x^2 - 9x - 5 = 0[/tex]
Step-by-step explanation:
To place the equation in standard form, we expand the operations. So
[tex]4(x-1)^2 = x + 9[/tex]
[tex]4(x^2-2x+1) = x + 9[/tex]
[tex]4x^2 - 8x + 4 - x - 9 = 0[/tex]
Combining the like terms:
[tex]4x^2 - 9x - 5 = 0[/tex]

4. A rectangle has length 3x + 4 feet. Its width is 7x feet. What is an expression in simplest form for the perimeter of the rectangle?
Answer:
2(3x+4)=P(perimeter)
Step-by-step explanation:
what I did was:
write out the expression 3x+4+7xcombine like terms in this case it's 3x and 7x10x+4put it in parentheses and put a 2 on the left side indicating distributive property for the equationit should look like this so far 2(10x+4)and you need to add what you are trying to find, so add =p to the right of the equationequation should look like this: 2(10x+4)=Ptwo questions please help

In this figure, angles R and S are complementary. Find the measure of angle S.
Answer:
S = 28 degrees
Step-by-step explanation:
The given angles are R = 62 and Q = 90 since there's the square showing its a right angle.
It says that R and S are complimentary which means together their total is 90 degrees. So there are two ways to do this;
R + S = 90
62 + S = 90
-62 -62
S = 28
OR
R + S + Q = 180
62 + S + 90 = 180
152 + S = 180
-152 -152
S= 28
Answer:
The answer I got was 28°
Step-by-step explanation:
1. Triangles add up to 180°
2. The "square" in the triangle means that angle is equal to 90°
3. Add the 90° angle with the 62° angle
4. Subtract the answer (152°) from the total (180°)
5. The answer is 28°

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.

A bit stuck on how to do this
Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.

Is the following graph exponential? Explain how you know.
Answer:
no
Step-by-step explanation:
the graph provided on the picture is y=x². It is visible, when the value of 'x' isdecreasing, the values of the function 'y' is increasing. If the function provided is exponential, then the values of the function 'y' is decreasing also.

(24.7C) The area of a rectangle is equal to x2 +
16x + 55 square units. If the length of the
rectangle is equal to x + 11 units, what expression
represents its width?
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5
I need help please A. The relationship is linear because each Y-value is two more than the value before. B. The relationship is linear because each y-value is two times the value before it. C. The relationship is exponential because each y-value is two more than the value before it. D. The relationship is exponential because each y-value is two times the value before it.
Answer:
D) the relationship is exponential because each y-value is two times the value before
Step-by-step explanation:
A and B are out because this graph is not a linear graph. D is out because that explanation represents a linear graph. An exponential equation will always multiply the value before it, not add.
