Mao counts by fives to 30.alana counts by tens to 40.who will say more numbers? Explain
Answers
Answer:
Mao will say more numbers
Step-by-step explanation:
Mao will say more numbers because, to get to 30, you must count by fives 6 times. For example, 5,10,15,20,25,30. There are 6 numbers there. On the contrary, Alana is only going to count 4 times. 10,20,30,40. 6 is greater than 4, therefore Mao will say more numbers. I hope this helps!

Prove the polynomial identity.
(4x^2−2)^2−(4x^2)^2=4(1−2x)(1+2x)
Drag and drop the lines of the proof in the correct order to complete the proof.
Answers
Answer:
(4x^2 - 2)^2 - (4x^2)^2 = 4(1 - 2x)(1 + 2x)
16x^4 - 16x^2 + 4 - 16x^4 = 4(1 - 2x)(1 + 2x)
4 - 16x^2 = 4(1 - 2x)(1 + 2x)
4(1 - 4x^2) = 4(1 - 2x)(1 + 2x)
4(1 - 2x^2)(1 + 2x) = 4(1 - 2x)(1 + 2x)

Answers
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The equation is given in "slope-intercept" form.
y = mx + b
where m is the slope, and b is the y-intercept.
__
For graphing, it is usually convenient to start with the y-intercept. The value of 'b' in your equation is +1, so the graph will go through the point y=1 on the y-axis. That point's coordinates are (0, 1).
The value of m represents the slope, or "rise"/"run" of the line. A slope of -2/3 means the line "rises" -2 units for each "run" of 3 units to the right. Then another point on the graph will be 3 units to the right of the y-axis, and 2 units down from y = 1. That point is (3, -1).
The line is drawn through these points you found on the graph.

∠a = 133°∠b = 15°∠c = 75°∠d = 58°Step-by-step explanation:
We don't know the definitions, properties, postulates, or theorems on your list, so we'll use the following:
a right angle measures 90°a straight angle measures 180°the acute angles in a right triangle total 90°an exterior angle of a triangle is equal to the sum of the remote interior anglesthe measure of an angle is equal to the sum of the measures of its parts.__
∠a = 180° -47° = 133°; reasons 2, 5. The angles form a straight angle.
∠b = 47° -32° = 15°; reason 4
∠c = 90° - ∠b = 90° -15° = 75°; reason 3
∠d = 90° -32° = 58°; reasons 1, 5. The angles form a right angle. If you want to get picky, we know it is a right angle by reasons 1 and 2. The marked right angle and the sum of 32° and ∠d together form a straight angle.

you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.
so 70 + 40 + 20 + 60 + 20 + 40 i believe.
this all equals 250.
ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.
f(x) = x² + 2ax + a² - a
g(x) = 4 - x²
Let variable a be a real number. Find the range of values of a such that the equation f(x) = g(x) has two different solutions.
***The answer should be -2 < a < 4, but I don't know why.
Answers
Step-by-step explanation:
f(x) = x² + 2ax + a² - a
g(x) = 4 - x²
f(x) = g(x)
x² + 2ax + a² - a = 4 - x²
2x²+2ax+a²-a -4 =0
the equation has two different solutions
=> (2a)² - 4(2)(a²-a-4) > 0
4a²-8a²+8a +32 >0
-4a²+8a+32 > 0
a²-2a-8 >0
(a-4)(a+2) < 0
the answer should be
-2 < a < 4

[tex]\frac{4}{10} +\frac{4}{9}[/tex]
So first you need to have a common denominator (the number on the bottom)
The least common denominator (LCD) would be 90.
So then the fractions would be: [tex]\frac{36}{90} +\frac{40}{90}[/tex].
Add.
You get: [tex]\frac{76}{90}[/tex]
