Answer:
x=5
Step-by-step explanation:
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
x=5
(-7x² + 3) + (4x² + 2x - 1)
-7x² + 3 + 4x² + 2x - 1
(-7x² + 4x²) + (3 - 1) + 2x collect like terms
-3x² + 2x + 2
hope this helps, God bless!
The answer is
(0,3)

Answer:
A = 35 units
Step-by-step explanation:
The variable "b" represents the length of the triangle's base and "h" represents the highest height of the triangle. The area of a triangle can be determined using the formula:
A = 0.5bh
The area of the top triangle (including the isosceles triangle and the orange triangle) is:
A = 0.5 x (14 units) x (3 units + 5 units)
A = 56 units
The area of the isosceles triangle is:
A = 0.5 x (14 units) x (3 units)
A = 21 units
Thus, the area of the orange triangle is the area of both triangles minus the area of the isosceles triangle.
A = 56 units - 21 units
A = 35 units
7-3b = 5b+15
move 5b to the other side
sign changes from +5b to -5b
7-3b-5b=5b-5b+15 ( combine like terms)
7-3b-5b=15
7-8b=15
move 7 to the other side
7-7-8b=15-7
-8b=15-7
-8b=8
divide both sides by -8
to get +b and by itself
-8b/-8=8/-8
Answer:
b=-1
