a² + b² = 1,520
Step-by-step explanation:
a + b = 40ab = 40a² + b²
= (a + b)² - 2ab
= 40² - 2(40)
= 1,600 - 80
= 1,520
Looking for the answer for the second one
Answer:
3 for the left one, and 5 on the right one.
Step-by-step explanation:
The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)
If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.
If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.
Use the given figure (triangular)to find the length of x. x+14 28
Step-by-step explanation:
Answer. Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2+b2=c2 a 2 + b 2 = c 2 , which is known as the Pythagorean Theorem.

Your grandfather placed $5,000 in a trust fund for you. In 12 years, the fund will be
worth $10,000. What is the rate of return on the trust fund?
Answer:
fv/pv=(1+r)^n
10,000/5000=(1+r%)^12
2=(1+r%)^12
r= 5.95
Step-by-step explanation:
fv/pv=(1 + r)^n
10000/5000=(1 + r%)^12
2=(1 + r%)^12
r=5.95

is this graph skewed or roughly symmetrical?
Answer: Roughly Symmetrical
Step-by-step explanation: There's no super easy way to explain why other than learning with experience but if you look at about the center of the graph, there are two peaks, and each side of the graph if split at about 68 which is the center, has 7 points each. This in conjunction with the shape and relatively normal spread makes it roughly symmetrical, not quire symmetrical but getting there.
there are 3 factors in the equation 5 x 3 x 2 = 30 true or false
Answer:
true
Step-by-step explanation:
the factors are simply what is being multiplied together. We can see there are 3 because we have 5,3,and 2. 30 is not a factor because that is the answer. I hope this helps!

In ∆PQR, m P = 60°, m Q = 30°, and m R = 90°. Which of the following statements about ∆PQR are true? Check all that apply.
A. PQ = √3 • PR
B. PQ = 2 • PR
C. QR = 2 • PR
D. QR = √3/2 • PQ
E. QR = √3 • PR
F. PR = √3/2 • PQ
Answer:
C. QR = 2 • PR
Step-by-step explanation:
According to given information we can draw a right triangle with angle measures as follows :
30-60-90 and for this special right triangle the side length would follow as:
The side length that sees angle measure 30 = a
The side length that sees angle measure 60 = a[tex]\sqrt{3}[/tex]
The side length that sees angle measure 90 = 2a
following this information the:
PR(sees 30 degrees) = a (can be represented as PR in this case)
and so
QR(sees 90 degrees) = 2a (2*PR in this case)
PQ(sees 60 degrees) = a[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] *PQ in this case)
The correct option is C. QR = 2 • PR

solve pls brainliest
Answer:
a) 5
b) 9
Step-by-step explanation:
The lines by the side decide absolute value, meaning distance from zero. for question A, simply add the integers to get -5. With the absolute value lines surrounding the question, you must make the answer 5 instead of -5 to show the distance from zero. In easier words, absolute value is just the positive number of an integer. For question B, the absolute value is surrounding just the -7, making it a positive 7. So, you simply just add 7 + 2 for question B, getting 9.

y=-10x+3
Answer:
53, 13, 3, -7
Step-by-step explanation:
When x = -5,
y = -10(-5) + 3
= 50 +3
= 53
When x = -1,
y = -10(-1) + 3
= -10 + 3
= 13
When x = 0,
y = 3
When x = 1,
y = -10(1) + 3
= -7

Lucy has read 500 pages of her summer reading assesment, and Angie has read 460 pages. Lucy has reads 10 per week for the remainder of the summer, and Angie reads 20 pages per week for the remainder of the summer. Write and solve an equation to show how many weeks it will take before the girls have read the same amount of pages.
Answer:
It would take four more weeks before the two read the same number of pages.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of extra weeks required before the two read the same number of pages.
Express the number of pages each would read between now and [tex]x[/tex] weeks into the future:
Lucy reads [tex]10[/tex] pages per week. Thus, she would have read [tex]10\, x[/tex] additional pages after [tex]x[/tex] more weeks.
Angie reads [tex]20[/tex] pages per week. She would've read [tex]20\, x[/tex] additional pages after [tex]x[/tex] more weeks.
It is also given that Lucy has already read [tex]500[/tex] pages. After reading [tex]10\, x[/tex] pages in the upcoming [tex]x[/tex] weeks, Lucy would have read a total of [tex](500 + 10\, x)[/tex] pages.
Likewise, after reading [tex]20\, x[/tex] pages in the upcoming [tex]x[/tex] weeks, Angie would have read a total of [tex](460 + 20\, x)[/tex] pages.
It is assumed that the two would have read the same number of pages after these [tex]x[/tex] more weeks. In other words:
[tex]500 + 10\, x = 460 + 20\, x[/tex].
Solve this equation for [tex]x[/tex]:
[tex]x = 4[/tex].
In other words, Lucy and Angie would have read the same number of pages after four more weeks.
