Answer:
To factor a trinomial in the form Ax^2 + Bx + C when the A = 1. You need to find the factors of C that when added or subtracted will give you B.
Factors of 21 are either 1,21 or 3,7. Since +3 and +7 will give you 10 then those will be the two factors you will use.
Factoring x^2+10x+21 will give you (x+3)(x+7)
Step-by-step explanation:

How many small cubes are needed to to completely fit in this rectangular prism?
Answer:
it has to be over 100
Step-by-step explanation:
i think this because if the 1 fraction cube is 1/3*1/3*1/3 big and the cube itself is 2 1/3*3 2/3*3 times long you would have to multiply that and the answer you get for the both of them divide them and see what you get
which would be 693.000000133
Explain how to solve 2x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution for x in your answer. Round your answer to the nearest thousandth.
Answer:
2x 2 x 2 x 2= 8 + 1 = 9?
Step-by-step explanation:
The solution of the equation 2x + 1 = 9 will be 4.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The equation is given below.
2x + 1 = 9
Simplify the equation, then we have
2x + 1 = 1
2x = 9 - 1
2x = 8
x = 8 / 2
x = 4
The solution of the equation 2x + 1 = 9 will be 4.

What are the x-intercepts for x2 - 5x + 6 = 0? (hint: factor
first)
Answer:x-intercepts (0,2) ; (0,3)
Step-by-step explanation:
x^2 - 5x + 6 =0
(x-2)(x-3) = 0
[-2 and -3 was the factors of 6, which make them equal to -5 when them add].
x-2=0 x-3=0
x=2 x=3
so x-intercepts (0,2) ; (0,3)

if you cycled for 3 hours and travelled 54 km calculate your average speed
Answer:
162 km per hour
Step-by-step explanation:
Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
Answer:
18km/h
Step-by-step explanation:
Well. Speed = Distance x Time
So if she travelled for 3 hours. In that time, she must have travelled 54km.
Average speed is given as kilometres per hour or km/h
So all we need to do is 54/3 which gives us 18km/h

Jamie writes -2°C > -5°C to compare the temperature on two January days. Explain why you agree or disagree with him
Answer:
I agree with Jamie
Step-by-step explanation:
Given the inequality expression -2°C > -5°C, to compare both temperatures, we are to determine whether we agree or disagree with him.
Note that negative values that are closer to zero on the number line are greater than those that are far from zero. Hence, since -2 is closer to zero on the number line than -5, this means that -2 is greater than -5 hence I agree with Jamie's temperature value comparison.

FIND THE ANGLE OF DEPRESSION. PLS HELP. I WILL MARK YOU A BRAINLEST
Answer:
62.2° (or 1.1 rad)
Step-by-step explanation:
Let’s call the three points A Allen’s house, B Bob’s house, T the traffic light and α “angle of depression”.
Since we have a right triangle BTA, let’s first find out the angle ∡BTA based on its opposite side AB = 7 km and the hyponenuse TA = 15 km.
∡BTA = arcsin(AB/TA) ≈ arcsin(0.4667) ≈ 0.4855 rad or 27.82°
Now since the text says the connecting line TA “is vertical to the road”, α is the rest of the right angle when ∡BTA subtracted.
α ≈ 90° - 27.82° = 62.18°
or α ≈ 0.5 π rad - 0.4855 rad ≈ 1.09 rad
See above for properly rounded values.
You spend $500 fixing up a bedroom to rent. Your cost for food is $10 per night. Ur family charges $60 per night. Write down equations to represent the situation
Answer:
y= 500+7x
Step-by-step explanation:
Given data
Total amount for the rent= $500
Cost of food per night= $10
Family charges per night=$60
Let the number of nights be x
and let the total charges be y
Hence, the expression for the situation is given as
y=500+10x+60x
y= 500+7x
the diameter of a cylindrical water tank is 8ft and its height is 11 ft what is the volume of the tank?
Using the formula for the volume of a right cylinder, we can determine the volume of the water tank.
Formula for the volume of a right cylinder: V = π (d /2)^2
h = π * (8/2)^2 ·11 ≈ 552.92
Therefore, the volume of the tank is approximately 552.92 ft.

Solve : 2 (m + 1) = 3(m - 1)
Step-by-step explanation:
hope this helps. if you have any questions don't hesitate to ask :))
Answer:
m = 5
Step-by-step explanation:
Given
2(m + 1) = 3(m - 1) ← distribute parenthesis on both sides
2m + 2 = 3m - 3 ( subtract 2m from both sides )
2 = m - 3 ( add 3 to both sides )
5 = m
