Answer: 22 feets of the border should be purchased
Step-by-step explanation:
A triangular flower bed (space for planting flowers) needs a thin metal border all the way around it. We want to look for the number of feet of the border that should be purchased. In this case, we are dealing with the distance round the border which is a triangle. The distance round the border is also known as the perimeter of the border. Therefore,
The perimeter of a triangle is the sum of all three sides.
The dimension of the sides are given as 7 feet, 6 feet, 9 feet long. Therefore, the perimeter is
7 + 6 + 9 = 22 feets

Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
Answer:
Given: Triangle ABC Prove: m∠A=64°
By the triangle sum theorem, the sum of the angles in a triangle is equal to . Therefore, m∠A+m∠B+m∠C=180°. Using the Substitution Property, (4x)°+90°+(x+10)°=180°. To solve for x, first combine like terms to get 5x + 100 = 180. Using the Response area, 5x = 80. Then, using the division property of equality, x = 16. To find the measure of angle A, use the Response area to get m∠A=4(16)°. Finally, simplifying the expression gets m∠A=150
