A. 7
The formula for the area of a triangle is 1/2*base*height You can find a base and height by finding the side length of SQ and SR by using the Pythagorean theorem to find the values of the hypotenuse of the two sides formed with the rectangle
a^2 +b^2 = c^2
2^2 + 2^2 = SR^2 Simplify
4+4 =SR^2
8 = SR^2 Take Square root of both sides
√8=SR
3^2 + 4^2 = SQ^2 Simplify
9+16 =SR^2
25 = SR^2 Take the Square root of both sides
5=SR
1/2*SR*SQ= Area of the triangle
1/2*√8*5 ≈ 7
If you would like to solve for x, you can do this using the following steps:
- x + 4 = 32
- x = 32 - 4
- x = 28
x = - 28
The correct result would be - 28.
The bottom is 2 times the size of the first one
2 (2x - 9) = 14
Distribute
4x - 18 = 14
Add 18
4x = 32
Divide by 4
x = 8
Answer:
no
Step-by-step explanation:
z^2 +1=4+3z
Substitute into the equation and see if it is true
3^2 +1 = 4+3(3)
9+1 = 4+9
10 = 13
This is not a true statement so this is not a solution
Answer:
I'm not totally sure but I do think the answer is yes
