Question 1 = 14 & -14
question 3= 15 & -15
question 5 = 13 & -13
Answer: b=13.75
Step-by-step explanation:
Use Pythagorean theorem
a^2+b^2=c^2
We know c, the hypotenuse, because the hypotenuse is opposite the right angle. It is 17
We also know a, one of the legs. It is 10.
Plug the number we know into the formula
10^2+b^2=17^2
100+b*2=289
Subtract the 100 on both sides
b^2=189
Take the square root of both sides
b=13.7477271
Rounded to the nearest Hundredth,
b=13.75
Hope this helped! :)
22 x 13 is 286 and 11 x r is 11r leaving you with 286=11r and then you have to divide each side by 11 and you get r = 26
The answer for this question is 4^3=64
2(3x+4). We need to multiply the outside by the inside because of the variable. 2 times 3x is 6x. 2 times 4 is 8. This gives us 2(3x+4).
