Answer:
Step-by-step explanation:
x²+5x-84
look for the factors of 84 that when you add together it will give +5
look for the factors of 84 that when you multiply together it will give -84
12 and 7
addition, multiplication
-12+7 = -5 -84
-12-7= -19 84
+12-7 = +5 -84 correct
then equate into the =5x and -84
x²+12x-7x-84
then factorize
x(x+12)-7(x+12)
(x-7)(x+12)
Answer:
x = 53°

alternate exterior angles are equal
Answer:
Width 2 4 6 8
Area 10 20 30 40
Step-by-step explanation:
Area of a rectangle = length × width
Calculate width when length = 5 inches
When length = 5 inches and width = 2 inches
Area of a rectangle = length × width
A = 5 × 2
= 10 square inches
When length = 5 inches and width = 4 inches
Area of a rectangle = length × width
A = 5 × 4
= 20 square inches
When length = 5 inches and width = 6 inches
Area of a rectangle = length × width
A = 5 × 6
= 30 square inches
When length = 5 inches and width = 8 inches
Area of a rectangle = length × width
A = 5 × 8
= 40 square inches
Given the same length and different width
Width 2 4 6 8
Area 10 20 30 40
Answer:
$169.06
Step-by-step explanation:
$12.25 x 10 = $122.50
$388 x 0.12 = $46.56
$46.56 + $122.50 = $169.06
If the integers have the same absolute value ... they're the same number
but with different signs ... then their sum is zero.
Example: (plus) 927 added to (negative) 927 = zero
If the integers have different absolute values ... they're different numbers with different
signs ... then their sum has the same sign as the one with the bigger absolute value.
Examples:
==> (plus) 92 added to (negative) 91
92 and 91 are 1 number apart on the number line.
The positive number is bigger than the negative number.
So the sum is +1 .
==> (plus) 35 added to (negative) 37
35 and 37 are 2 numbers apart on the number line.
The negative number is bigger than the positive one.
So the sum is -2 .
