Answer:
-1
Step-by-step explanation:
4x-1=-4
-4+3=-1
The correct statement is C. <span>If an angle is an acute angle, then the angle measures less than 90 degrees.
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute. </span>
Step-by-step explanation:
Where is your question in order to answer it
a= 16x+16
b= 40x + 15
Step-by-step explanation:
We know that perimeter of a rectangle is
So therefore
Answer= A) that is perimeter is 16x+16
We know that area of a rectangle is l×b
So therefore
Answer = b) that is area is 40x + 15
Use ac method
for ax²+bx+c=0 when a≠1
multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b
2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that
2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero
y+3=0
y=-3
2y+3=0
2y=-3
y=-3/2
y=-3 and -3/2
it's factored form is (x+3)(2x+3)
