Answer:
4th option
Step-by-step explanation:
7x(8x² - 4y² + 3y - 5) ← multiply each term in the parenthesis by 7x
= 56x³ - 28xy² + 21xy - 35x
Answer:
y=-3/4-2
Step-by-step explanation:
The slope or m is -3/4
The y-intercept or b is -2 so when using the formula y=mx+b you get y=-3/4-2
Answer:

Step-by-step explanation:
In triangle ABC, OA = OB = OC = 10 in. These segments are radii of sircumscribed circle. So, R = 10 in.
The sum of all interio angles is 180°, so
m∠C=180°-35°-65°=80°
Use the sine theorem,

Thus,

Therefore,

Answer:
5h+11
Step-by-step explanation:
You add the like terms so 1h+5h-1h= 5h. Then you just add 11 into the equation
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base dimension and h=height
1) 10(12)/2=60mm^2
2) 14(34)/2=238in^2
3) 9.5(19.25)/2=91.4375yd^2
4) 4.9(23.7)/2=232.26m^2
5) 285=15b/2, 15b=578, b=38ft
6) 17h/2=18.7, 17h=37.4, h=2.2cm
7) 12.25b/2=128.625, 12.25b=257.25, b=21in
