If you combine 2z and -z you get z.
The rectangle has the dimensions 4 x 3.
The measure of 6 ft is the triangle plus the square's length.
The rectangle's length is 3.
To find the triangle's width, solve this: 3 + x = 6
Subtract 3 from each side to get x = 3.
The dimensions of the triangle is 3 x 4.
The area will be half of 3 x 4, so 12 / 2 or 6.
The rectangle's area is 12 because its dimensions are 3 x 4.
12 + 6 = 18 feet total.
Hope this helps!
The solutions are:
x = −4,x = 7
Explanation:
X^2−3x−28= 0
We can first factorise this expression by splitting the middle term and then find the solutions:
= x^2−7x+4x−28=0
= x( x−7) + 4( x − 7)=0
=(x+4)(x−7)
Now, we can equate the two factors with zero and find the solutions:
x+4=0,x =−4x−7=0,x=7
Answer:
-12 and -11
Step-by-step explanation:
square root(-123) = -11.0905365
so then it would be -11 then -11.0905365 then -12
