I am loosing soo much of my points by doing this I was at 102 now I am at 40 please answer these correctly

Answers

Answer:

Step-by-step explanation:

If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.

A 4 + 3 ≥ 1 True, it's greater, but it can't be equal to.

B 3(4) ≥ 1 It's greater once again, can't be equal to.

C 4 - 3 ≥ 1 If x can also be greater than 4, then it works both ways. Equal and greater than.

Number 8 is A. 4, when a letter/variable is right beside number you multiply it. So since n=4, the equation should be 7 x 4 + 14= 42...also keep in mind the answer has to be less than 56

So A.4

Answer:

choice 2) x = 60°

Step-by-step explanation:

the complement of an angle is an angle that when added to the original angle = 90°

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

A' (5, 3)

B' (2, 3)

C' (2, 1)

The figure can be composed of different shapes.

What shapes can the figure be decomposed into to find the area? What is the area?
A. one triangle and one square; 24 square feet
B. one triangle and one rectangle; 30 square feet
C. two triangles and one square; 36 square feet
D. two triangles and one rectangle; 42 square feet

Answers

the answer is a because if you split the shape you would get one triangle and one square or rectangle

The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a figure.

We can divide the figure in to one triangle and one rectangle by drawing a vertical line.

Area of a rectangle = Length × Width

Here, length = 8 feet and width = 3 feet

Area of rectangle = 8 × 3 = 24 feet²

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

Base = 12 - 8 = 4 feet and height = 3 feet

Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²

Total area = 24 feet² + 6 feet² = 30 feet²

Hence the area is 30 feet².
