9 plus How many sides nine times
Answer:
4cm
Step-by-step explanation:
Given data
L=(2x+3)
W=(x-1)
P=28cm
A= L*W
A= (2x+3)*(x-1)
open bracket
A= 2x^2-2x+3x-3
collect like terms
A= 2x^2+x-3
P= 2L+2W
P= 2*(2x+3)+2(x-1)
P= 4x+6+2x-2
collect like terms
P= 6x-4
but p= 28
28= 6x-4
28-4= 6x
24= 6x
x= 24/6
x= 4cm
Hence x= 4cm
The shapes are similar.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Therefore,

Simplify:

Cross multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 57x - 42x
420 = 15x
x = (420÷15)
x = 28
<span> 4x + 4y = 20
If I'm not mistakened, this is in it's standard form.
Slope intercept form </span>→ y = mx + b
Let's transform this into that form.
4x + 4y = 20
4y = -4x = 20
y = -x + 5
The slope intercept form would be ⇒ <span>y = -1x + 5 </span>
Answer:
Graph the line y = 3r
