F(x)=(3(-1))-2 so the answer is 5
Answer:
the answer is 12
Step-by-step explanation:
Simplify both sides of the equation.
12(b−10)+2b=25
(12)(b)+(12)(−10)+2b=25(Distribute)
12b+−5+2b=25
(12b+2b)+(−5)=25 (Combine Like Terms)
52b+−5=25
52b−5=25
add 5 to both sides.
52b−5+5=25+5
52b=30
multiply both sides by 2/5.
(25)*(52b)=(25)*(30)
b=12
Answer:
The corresponding pair of sides are in the same ratio.
Step-by-step explanation:
For two triangles to be similar, the theorem that is required is the corresponding sides of the two triangles are in the same ratio.
Now, see the diagram of two triangles given with the question.
The ratios of the corresponding sides are 
If two pairs corresponding sides are in 5 : 4 ratio, then the third pair of corresponding sides will also be in 5 : 4 ratio.
Therefore, the two triangles are similar. (Answer)
To solve this problem, we need to know the formulas for the areas of each of these shapes. The formula for the area of a circle is πr², the area of a rectangle is b * h, the area for a square is s², and the area for a triangle is 0.5bh. Now we can solve.
1) This is a circle, so the area is πr² = π(6)² = 36<span>π square feet
2) This is a square, so the area is s</span>² = 12² = 144 square yards
3) This is a rectangle, so the area is b * h = 6 * 14 = 84 square inches
4) This is a rectangle, so the area is b * h = 7 * 3 = 21 square inches
5) This is a circle, so the area is πr² = π(4)² = 16<span>π square feet
6) This is a triangle, so the area is 0.5bh = 0.5 (8 * 8) = 0.5 * 64 = 32 yd.</span>²
7) This is a triangle, so the area is 0.5bh = 0.5 (5 * 10) = 50 * 0.5 = 25 yd.²
8) This is a rectangle, so the area is b * h = 10 * 2 = 20 in²
9) This is a square, so the area is s² = 9² = 81 ft²
