Answer:
[tex]95ft^2[/tex]
Step-by-step explanation:
We need to multiply 10 feet by 9 feet 6 inches.
6 inches is half a foot so technically 9 feet 6 inches is 9.5 feet.
Multiply 10 by 9.5.
(10)(9.5) = 95
Therefore the answer is 95ft squared.

2. Use the distributive property to evaluate the expression.
A) 4(x-2)
B) 3(y+9)
C) -2(3-r)
Answer:
a) 4x-8
b) 3y + 27
c) -6 + 2r
Step-by-step explanation:
Here, we want to use the distributive property to evaluate the given expressions
Mathematically, the distributive property is;
(a + b) * c = (a * c) + (b * c)
So we use this on each of our questions;
a) 4(x-2)
= (4 * x) - (4 * 2) = 4x-8
b) 3(y + 9)
= (3 * y) + (3 * 9)
= 3y + 27
c) -2(3-r)
= (-2 * 3) - (-2 * r)
= -6 + 2r

The longest leg of a right triangle is 12 inches. The hypotenuse is 3 inches longer then twice the shortest leg. How long is the shortest leg and the hypotenuse of the triangle.
Answer:
Shortest Leg: 5 inches, Hypotenuse: 13 inches
Step-by-step explanation:
A right triangle follows the pythagorean theorem, a^2+b^2=c^2. C is the hypotenus. A combination found using this is 5, 12, and 13. To double check this, we know that the hypotenus is 2x+3, where x is the smallest leg.

Use the graph to evaluate the function for the given input
value.
fl-1) =
f(1) =
Answer:
f(-1) = -8
f(1) = -12
Step-by-step explanation:
-1 and 1 are inputs to the function f which is shown on the graph.
The inputs are on the x-axis so when x = -1, the graph shows that the function f at -1 is approximately -8.
When x = 1, the function f is approximately -12.

solve 2x^2+9x-7=0
Give your solutions correct to 3 significant figures.
Answer:
X = -1 or X = -3.5
Step-by-step explanation:
2x^2 + 9x + 7 = 0
ac = 14
b = 9
find a two numbers which when you multiply you get 14 and add you get 9.
so it will 2 and 7. (they replace b which is 9x)
therefore: 2x^2 + 2x + 7x + 7 = 0
find common factors using each 2 from the four.
2x( x + 1) + 7 (x+1) = 0
so it will be (2x + 7) (x+1) = 0
find x,
i) 2x +7 = 0
x= -3.5
ii) x + 1 = 0
x = -1

Answer:
10x + 39 - y
Step-by-step explanation:
Answer:
10x - y +39
Step-by-step explanation:
Solve: |11x + 10| = 22
To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.
Case 1: (11x + 10) is positive:
In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.
Case 2: (11x + 10) is negative:
Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.
Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.
