1. A rectangle has side lengths of 3x2 + 5x - 1 and -7x+1. Which of the following expressions represents the area of the rectangle?
a. 3x²-21
b. 3x² - 35x-1
c. -21x³ - 38x²- 2x - 1
d. -21x³ - 32x² + 12x - 1
please help
21x³-42x²+12x-1
[area of rectangle =length ×breadth
=(3x2 + 5x - 1)(-7x+1)
=3x²(-7x+1)+5x(-7x+1)-1(-7x+1)
=-21x³+3x²-45x²+5x+7x-1
=-21x³-42x²+12x-1

Answer:
640 units squared
Step-by-step explanation:
First, the formula of a trapezoid is (a + b) x 2 divided by h
So, 40 + 24 = 64
64 x 20 = 1280
and 1280/2 = 640
Hope this helps!

An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 6.
Event B: The sum is not divisible by 4.

James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.
Answer: $339
Step-by-step explanation:
Given
The total length of the journey is 10 miles
fixed pledges are $300
variable pledges are $13 per mile
Point slope equation form is
[tex]\Rightarrow y=mx+c[/tex]
Here the total charge corresponds to y and miles walked corresponds to x
So, we can write
[tex]T=13\times m+300[/tex]
where,
[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]
for 3 miles distance
[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

Find the area of the parallelogram.
Answer:
36 ft^2
Step-by-step explanation:
I) Find dimensions:
The base is 9 feet, and the height is 4 feet.
(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)
II) Find area:
Area = base x height
A = B x H
36 = 9 x 4
III) Find unit:
Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)

Could you please help me with the step-by step? This problem is giving me trouble.
Write both sides as powers of 2. First,
1/2 = 2⁻¹
16 = 2⁴
so the equation can be rewritten as
(1/2)ˣ = 16²
(2⁻¹)ˣ = (2⁴)²
Recall that [tex](a^b)^c=a^{bc}[/tex], so that
2⁻ˣ = 2⁸
The bases are the same, so the exponents must be equal:

3(x + 1) - 2x = -6 what’s the answer??
Answer:
x=−9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
x+3−3=−6−3
x=−9

The measure of an angle is 34.7°. What is the measure of its supplementary angle?
Answer:
Let the supplementary angle be x.
x+34.7°=180
or, x=180-34.7°
or, x=145.30°
:. x=145.30°
