46
Step-by-step explanation:
all angles must add to 180
32+102= 134
180-134= 46
correct me if im wrong:)
Step-by-step explanation:
is the number of unit squares that cover surface of a figure.
Answer:
length: 200
width: 65
Step-by-step explanation:
length: 3w + 5
width: w
perimeter = 2L + 2W
530 = 2(3w + 5) + 2w
530 = 6w + 10 + 2w
530 = 8w + 10
520 = 8w
w = 65
length: 3w + 5 = 3(65) + 5 = 200
width: w = 65
We know that 1 million has 6 zeros. This means 1 million has 7 place values: one for the 1 and 6 for the zeros.
50 has 1 more place value than one, so 50 million has 1 more place value than 1 million.
So, 50 million has 8 place values.
Answer:
a = 4 and b = - 30
Step-by-step explanation:
Expand the left side and compare like terms on both sides, that is
(x + 2)(x - 3)(x + 5) ← expand the first pair of factors using FOIL
= (x² - x - 6)(x + 5) ← distribute
= x³ + 5x² - x² - 5x - 6x - 30 ← collect like terms
= x³ + 4x² - 11x - 30
Compare like terms with x³ +ax² - 11x + b
4x² and ax² ⇒ a = 4
+ b and - 30 ⇒ b = - 30
