I Need Help On Both Of These Plss

Answers

Answer 1

Answer:

1. When combining 5+2+3 it equals 10; and when solving 5+(2+3) you solve what's in the parenthesis first. So the new problem is 5+(5), which equals 10.

2. Same goes for the second one, 11-2 is 9, then you just add the a because both have the same variable

hope that helped :) have an amazing day

Answer 2

Answer:

for 1: yes they are the same

for 2: true

Step-by-step explanation:

for 1: 5+2+3=10 and 5 +(2+3) = 10 because 2+3=5 so 5+5=10 therefore they are the same

For:2 9=11-2 because 11-2=9

Solve the quadratic formula

X^2-5x-14=0

Answers

Answer:

Step-by-step explanation:

Sum = -5

Product = -14

Factors = 2 , (-7)      because 2*(-7) = -14 and 2 + (-7) = -5

x²  - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) -7(x + 2) = 0

(x + 2)(x - 7) =0

x + 2 = 0           ;  x -7 =0

     x = -2  ;            x  = 7

3) Reflexive Property

4) SAS

Step-by-step explanation:

ST ≅ TS

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

Example: a = a  In this case, it could be seen as ST ≅ ST because they have/are the same side(s).RST ≅ UTS

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

Example: RST ≅ UTS (both have S and T) Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

Would y^10/y^10 become 1?

Answers

Answer:

yes

Step-by-step explanation:

If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y

If you are multipling the answer will be y^10  because 10 plus 10 is 20 and you keep the base which is y

#17. The height, H metres, of a certain species of Fir
tree can be estimated from the formula.
h= 35d , where d metres is the diameter at the
base. use the formula to determine the approximate
height of a fir tree with base diameter 3.2 m.

Answers

Answer:

The approximated height of the tree is of 112 meters.

Step-by-step explanation:

The height of a tree with a base diameter of d meters is approximated by the following formula:

[tex]h = 35d[/tex]

In this question:

Base diameter of 3.2m, so [tex]d = 3.2[/tex], and the height is in meters.

[tex]h = 35d = 35(3.2) = 112[/tex]

The approximated height of the tree is of 112 meters.
