Answer:
4x²-5x +4 X=3
Step-by-step explanation:
The expression below has 3 terms. The first step is to plug in the 3 for all the x´s. Then find what 3 squared is. Next is to multiply the 9(3²) with the 4 to get 36. Now the expression is 36 - 5 x 3 + 4. Next is to multiply the -5 and the 3 to get 15. Now combine all like terms to get 55.

Amanter on the edge of a mol has the shape a rectangular prism. It is 9 inches high, 2 inches wide, and 14 feet long. How much water can the gutter hold in cubic inches in gallons? Use the fact that
1231 inches
The gather canto cubic inches of water
Answers
Answer:
1.1 gallons
Step-by-step explanation:
Given that the shape of the gutter is in the form of a rectangular prism with length 14 feet, width 2 inches and of height 9 inches.
The volume of the gutter = length x width x height
= 14 x 2 x 9
= 252
The volume of the gutter = 252 cubic inches
But with the given fact, we divide the volume determined by 231 inches.
Then,
the required volume in gallons = [tex]\frac{252}{231}[/tex]
= 1.090908
The gutter can hold water of 1.1 gallons.
For which value of x is the row in the table of values the incorrect? The function is quadric function y=5x^2
A. x=5
B. x=0
C. x=3
D. x=2
Answers
Answer:
x = 2
Step-by-step explanation:
Substitute x = 2 into y = 5x² , that is
y = 5(2)² = 5(4) = 20 ≠ 10
Thus (x, y ) = (2, 20 ) and not (2, 10 )

90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,

Answers
Answer:
a = 15, b = -14
Step-by-step explanation:
From the question,
a/5 - b/2 = 10
Multiply all through by 10
(a/5)10 - (b/2)10 = 10×10
2a - 5b = 100...................... Equation 1
a - b = 29 ........................ Equation 2
Solving equation(1 ) and equation (2) simultaneously
using elimination method,
multiply equation (2) by 2.
2a - 2b = 58.................... Equation 3
Substract equation 3 from equation 1
2a - 2a -5b-(-2b) = 100-58
0 - 5b+2b = 42
-3b = 42
b = 42/-3
b = -14.
Substitute the value of b into equation 2
a - (-14) = 29
a +14 = 29
collect like terms
a = 29-14
a = 15.
Hence, a = 15, b =-14

Adrian had 4 hits in 10 bats.
Answers
Answer:
Hence, both Marlon and Adrian both have the same at bats percentage.
Step-by-step explanation:
Marlon's at bats :
Number of at bats = 15
Hits = 6
Hit percentage = 6/15 * 100% = 40%
Adrian :
Number of at bats = 10
Hits = 4
Hit percentage = 4/10 * 100% = 40%
Hence, both Marlon and Adrian both have the same at bats percentage.
