Answer:
x = 10
Step-by-step explanation:
4x + 3(x - 1) = 67 ← distribute parenthesis and simplify left side
4x + 3x - 3 = 67
7x - 3 = 67 ( add 3 to both sides )
7x = 70 ( divide both sides by 7 )
x = 10
The figures that can match are those which are similiar in shape.
Observe that polygons 1 and 4 have similar shape, hence those are the answer.
<h2>A is the answer.</h2>
Answer:
-5 < x < 9
Step-by-step explanation:
By Hinge theorem,
"If two sides of a triangle are congruent to the two sides of another triangle, and the included angle of one triangle is larger than the included angle of the second, then the 3rd side of triangle one will be larger than the third side of the second"
23 > 21
Therefore, 42° > (3x + 15)°
42° - 15° > 3x
27 > 3x
9 > x
And (3x + 15) > 0
3x > -15
x > -5
Therefore, range for x will be,
-5 < x < 9
2x+4y=16
2x+4(4)=16
2x+16=16
-16=-16=2x=0
0.8 squares shaded out of 10
You just do 4x2 which is 8
Then add the 0. In front of 8
Easy as that
