Answer:

a = 4

Step-by-step explanation:

Here, we want to write and solve the given equation

a - 2.5 = 1.5

a = 2.5 + 1.5

a = 4

To check, we simply substitute a = 4

That would be;

4-2.5 = 1.5

This is correct

In the figure to the right, AB = 7 1/2 m, BC = 2 1/4 m, and DE = 1 1/4 m. Find the perimeter of the figure if all angles are rig
Andreas93 [3]

Answer:

Perimeter=22 m

Step-by-step explanation:

Perimeter Of A Figure

Perimeter is the distance measured around a shape. If the figure is line-shaped, the perimeter can be obtained by adding the individual lengths of each segment around the shape.

The figure shown is surrounded by line segments. We only have to add them all to find the perimeter. But we don't need each individual length to do so. We may notice the following (given all angles are right):

The sum of HG+FE+DC equals AB. So the upper and lower lengths are twice AB, or equivalently: 2*7 1/2 m =15 m

It can also be noted that AH+GF=BC+DE=2 1/4+1 1/4 = 3 1/2 m. It means that the two lateral lengths are twice this value: 2* 3 1/2 = 7 m

Thus, the total perimeter is 15 m + 7 m = 22 m

Can someone please help. Find the value of x.
Liono4ka [1.6K]
Let thd centre be O
Draw a line joining B and C
Angle OCB= 46 (alternate angles)
Angle COB= 180-46-46= 88
Angle BOA= 180-88-46=46
46 =x+4
x=42

The functions f(x) and g(x) are defined below.
schepotkina [342]
For this case we have the following polynomials:
 f (x) = 21x ^ 2 + 13x - 20

g (x) = -3x - 4
 To divide the polynomials we must follow the following steps:
 1) Same base, the exponents are added.
 2) Only terms that have the same exponent can be added or subtracted.
 3) If the remainder is zero, the division is exact.
 Answer:
 
f (x) / g (x) = -7x + 5

 Note: see attached image for the solution.
