Answer:

1) 117

2) 9

3) 45 or -45

Step-by-step explanation:

a=9

b=6

1) a²+b²=9²+6²=81+36=117

2) (a-b)²=(9-6)²=3²=9

3) a²-b²=81-36=45

It’s also possible that a=6 and b=9, in which case

1) (same)

2) (same)

3) 36-81=-45

A triangle has vertices at points (0, 0), (a, b), and (2a, 0). Select all points that lie on the sides of the triangle. A. (a, 0

RSB [31]

Answer:

A. (a, 0)

D. (a/2,b/2)

Step-by-step explanation:

(a, 0) lies on one side of the triangle, because it is between (0,0) and (2a,0)

(0, b) doesn't lie on one side of the triangle, because only the only point with x-coordinate = 0 is (0,0)

(–a, b) doesn't lie on one side of the triangle, because only positive values are valid

Imagine the triangle with vertices (0,0), (a, 0) and (a,b). Let's call β the angle at vertex (0,0)

tan(β) = b/a

For triangle with vertices (0,0), (a/2, 0) and (a/2,b/2)

tan(β) = (b/2)/(a/2) = b/a

then, (a/2,b/2) lies on one side of the triangle

For triangle with vertices (0,0), (a/3, 0) and (a/3,b/4)

tan(β) = (b/4)/(a/3) = (3/4)*(b/a) ≠ b/a

then, (a/3,b/4) doesn't lie on one side of the triangle

Solve -3(-8b+7)=3(2b-1)

nekit [7.7K]

Answer: $b=1$

Step-by-step explanation:

Given the equation $-3(-8b+7)=3(2b-1)$ you need to solve for the variable "b".

You need to apply Distributive property on both sides of the equation:

$-3(-8b+7)=3(2b-1)\\\\24b-21=6b-3$

Now you need to add 21 to both sides of the equation:

$24b-21+21=6b-3+21\\\\24b=6b+18$

Subtract $6b$ from both sides:

$24b-6b=6b+18-6b\\\\18b=18$

And finally, you can divide both sides of the equation by 18:

$\frac{18b}{18}=\frac{18}{18}\\\\b=1$

How to do 15 1/2 - 2 1/10 how to do it

lisov135 [29]

First, you need to make the fractions have the same denominator:

15 1/2 ---> 15 + (1/2 x 5) = 15 5/10

2 1/10 ---> 2 1/10

Then you need to subtract them from each other:

15 5/10

- 2 1/10 (or) 15 5/10 - 2 1/10 = 13 4/10

13 4/10

This gets the answer: 13 4/10

Evaluate the equation. 3/5h = 18/35 A) h=6/7 B) h=7/8 C) h=9/10 D) h=98/105

rjkz [21]

Equations -

I like to find the decimal expression of the fractions, to make this easier.

$0.6h = 0.514285714285$

Divide each sides by 0.6

$h = 0.857142857142 \: or \: \frac{6}{7}$

Answer: 6/7
