Answer:
the answer to your questions are below
Step-by-step explanation:
1.-
x = 3x - 60
3x - x = 60
2x = 60
x = 30
A = 30
2.-
- x + 26 = 2x - 10
2x + x = 26 + 10
3x = 36
x = 36/3
x = 12
D = 2(12) - 10
D = 24 - 10
D = 14
3.-
5x + 10 = 7x - 12
7x - 5x = 10 + 12
2x = 22
x = 22/2
x = 11
4.- 4x + 7 = 5(x - 4)
4x + 7 = 5x - 20
5x - 4x = 7 + 20
x = 27
5.- 6(x - 2) = 3x + 30
6x - 12 = 3x + 30
6x - 3x = 30 + 12
3x = 42
x = 14
DHG = 6(14 - 2)
DHG = 6(12)
DHG = 72
Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
- The shape clearly occupies the space of 5-centimeter squares.
We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Answer: w=66/9
Step-by-step explanation: 8/9=w-2/6
8(6)=9(w-2)
48 =9w-18
48+18=9w
66=9w
w=66/9
or w=7(3/9)

Answer:
12
Step-by-step explanation:
15 feet total amount combined by pole and
birdhouse
4 foot tall person makes 5 feet long
