Answer:
46
add all the number together and divide by how many there is
Answer:
volume = area of rectangle × height
= (x × x ) × 1/2x
= x² × 1/2x
= 1/2x³
the answer is the first option
Answer:
x = -5, 1
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from
.
-1 and 5 multiply to -5 and add to 4.
![x^2+4x-5 = (x+5)(x-1)](https://tex.z-dn.net/?f=x%5E2%2B4x-5%20%3D%20%28x%2B5%29%28x-1%29)
The zeros are the factors set equal to 0 and solved.
(x+5) = 0
x=-5
(x-1) = 0
x=1
Answer:
brainliest plzzz
Step-by-step explanation:
2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:
y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like
y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.
y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.
2y = -x + 18 then add x to both sides.
x + 2y = 18 done.
Answer:
He has 16 moose photos
Step-by-step explanation:
He has 4 bear photos since 4 times 4 equals 16. The eagle photos would have to be 30, which is divisible by 6.
16 moose+4 bear+30 eagle=50 photos
