Answer:
b=7
Step-by-step explanation:
Plug 3 into a since a=3.
2(3)+b=13
Then solve for 2(3)
6+b=13
Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)
b=13-6
b=7
Answer: -5t + 23= 18
Step-by-step explanation: 18 + -3 + -5t + 8 =
(-5t ) + (18 + -3 + 8) = -5t + 23 → 18
Answer:
25
Step-by-step explanation:
If you add 25 to both sides, you get
x^2-10x+25=26.
Now, you can simplify the left side into a perfect square
(x-5)^2=26
Answer:
52.9 inches .
Step-by-step explanation:
Given that the triangular indentation has an area of 100 in.² and the base and height of this traingle are represented by expressions 3x and x+3 respectively . We need to find out the <u>perimeter </u>to the nearest tenth.
As we know that the area of triangle is ,
Substituting the respective values,
On using the <u>Quadratic</u><u> formula</u> , we have;

On simplifying above , we will get ,

Since sides can't be negative, therefore,

Therefore ,
Next let's find out the <u>hypotenuse </u>using Pythagoras theorem, as ;
Now we may find perimeter as ,
